title of mobile bar

Where can I enter the caption in the top bar of the mobile menu?
I had it here (see appendix) but now it only appears in the expanded menu and not in the topbar.

I also attach a picture from DT

Hi
Please give me the url of the page so that I can check
Please also try without the special character to see if this can be in cause
CEd

a special character is not the problem.
Version is 1.5.8.
I think it worked correctly in the previous version.

link is ernst7.8u.cz/

I give you the previous version so that you can test to confirm if it works
www.dropbox.com/s/f1okw759u5m8kxp/mobile...k-pro_1.5.7.zip?dl=0

I have inspected but I don't see why this occurs. If the problem is the same with the 1.5.7, please try to play with the mobile menu options to see if you manage to make the title visible
also try to create a new mobile menu, using another menu, another settings, and tell me

any information would be useful

I have setup a mobile menu similar to yours but I have the title shown ...

good day.
I removed the special characters, it didn't help.
I created a new menu and the text did not appear either.
the maximum version is not the cause of the error
I restored a backup that is about 14 days old to c asino2.8u.cz and it shows okay there.
I made a copy of the existing website at c asino3.8u.cz, tried to uninstall some things there and the text is still not displayed.
I don't know how to do that, can you please help me?

I can give you access.

ps I had to edit the url names because of your antispam, there is no space in the url

thanks for the test
