Unable to delete an access mode I created - by: dnaton

Hello

I created a new access mode "GestionnaireR".

After many tries without success to use it in screen "Data access (project dependant)" (this access was visible in the list, but impossible to save), I decided ti delete it.

But when I go on the screen "Access mode", I see it but can't delete . Projeqtor tell me this item seems to be recently deleted (see image below).

I didn't delete it....but I want to....but I can't



I understand now why it didn't work in screen "Data access" but I don't understand why it is like that...and how delete it really.

Could you help me ?

Thanks
