Hello
This morning, a colleague asked me if I knew why he has tabs on his interface without designation.
He recently changed his PC but can't remember if his interface was like this before.
Hello
If they are empty, they can be hidden by right-clicking on the banner area and then "customize".
Afterwards, if you have a configuration file for the interface common to all users, you can always have it load, it will solve the problem.
I've never had this kind of problem, if it's a standard installation that leads to this result, maybe see to reinstalling SW.
Or right-click on the tabs, Custom..., then right-click on the tab and delete or hide but if empty you might as well delete it.
And this time @Cyril.f I posted it in the right topic! 
Thank you for your answers.
We solved the problem thanks to your advice!
On the other hand, it lacks a lot of function in its interface
Under the "functions" tab, it doesn't have the block with the shortcuts to "Leave", "Repeat", "Rib"...
We tried the "Customization" tab where you can show everything and/or restore the default settings
But nothing works
Hello
Have you saved your settings by clicking on the cogwheel, if so you can restore your settings or recover those of a colleague to customize them and then save them to have a backup
For the restoration of a profile, following the @ac_cobra_427 method, you must however have a specific profile with the file paths on the network (not local) otherwise it can cause even more important problems.
Ideally, you should make a profile specific to each new version of SW and then save and share it.
We had saved my colleague's profile with this method before he changed PCs
However, he did not have these missing items before saving his profile...
These tabs probably refer to things that SW in its new version can no longer find.
