{generator:true} in all template fields

When I create a new template with a password field I enter the field name "xyz", activate the security switch => OK and enter "text {generator:true}" as field format. After saving of the new template the password field always contains only "text". The extension "{generator:true}" will never be saved. So it is not possible to implement the Password Generator.

Version: KeepassDX 3.5.0 and 3.4.5
Device: Samsung Galaxy S4 (Modell: GT-I9505)
OS: LineageOS 18.1 (Android 11)

No source files or tests are named. First reproduce the issue in the Android app by creating a password template with a format containing `text {generator:true}`, then trace how template fields are saved and loaded. Done means the extension is preserved after saving and the password generator can use it.
