Web part title changes not reflected to some users in multilingual SharePoint environment

SharePoint is not broken - it just does't work

​​When changing the web part title on a web part on a classic SharePoint page, changes seem to be saved for you. In reality, they are only reflected to some users.. And some users, on some devices, see the old title, whereas some see the new one. It’s a confusing situation and difficult to debug.

Why do web part titles get changed seemingly randomly?

Imagine this: You have a SharePoint environment, where you have multiple different languages set up. You also have users with multiple different workstation configurations – including multiple different languages. Different users, however, quite randomly see different revisions of web part titles in a very weird manner. This happens seemingly randomly even on new client devices, so no client-side caching is the reason.

This actually likely works as designed, it’s just kind of a confusing implementation. We’ve got Microsoft to blame for that, and their pretty bad documentation.. SharePoint actually localizes (and hence saves) Web part titles per-language. 

Explanation

After some investigation, we got a pretty good description of this fuctionality from Microsoft. This is the explanation that Microsoft’s Support Engineer offered us:

After closely analyzing the behavior encountered and creating a test enviroment similar to the productive one, we could notice that there were situations where the users could see the changes performed in the Title field. Moving forward with the analysis, we concluded that the behavior was triggered by the following variables:

(1) The local language set as preferred by the users and (2) the alternative language set on the site collection. ​

This behavior is due the resource files that we have depending on the alternative language that we have selected on the site. For eg. in the French site, if we change the web part title using the resource file in English, a user which has the French resource/local language setting defined for French will not see this change. For them, it’s pointing to a different resource file.

Basically, the resolution for this situation would be to disable the alternative language set on the site collection. This setting is located under Site Settings – Under Site Administration – Language settings – Alternate language(s).
 
This will help us make sure we are accessing the right resource file when performing certain changes and the changes will be visible by all the users. This is also explaining why the same user was able to see the web part title by connecting to a different machine because the local language settings (including the browser preferences) were influencing this. 

Solution

So, in short, this functionality is slightly broken (or at the very least, quite confusing) by design, and if you want to get your web parts to be updated for all users, disable alternate languages and just force your users to see everything in the default language. Or use multiple browsers with multiple language settings to edit the titles!
