Tab containing only tabs not showing

[CharlesGag]

Hello,

In the form manager, when you make a tab containing only tabs, the tab name do not show.

If you add a field in the said tab, it shows (incorrectly - it should be before field 1)

I'm not sure it if's a specific phone related issue, I have not try this on a tablet (only pixel 3a).

The screenshot above are from a project I just created for testing purpose. I first encounter this with that project below. I have a rule set so that if you choose between "rigide" or "flexible", it shows only the according tab. However it's not working because of that issue. The rules works fine in QGIS. I have version 3.26.1.

Thank you everyone, keep up the good work.

Finally tried this on a Ipad, same result.
