I just installed your ingenious extension (PHP version 7.4.13, phpBB version 3.3.2). It works without any problems and does what it should. Thanks a lot for this great piece of software.
Anyway I did notice a small "phenomenon". If I allow (select) more than one country code, more than my selected country codes are automatically added. Example:
1. germany selected -- only the one entry is selected
2. Germany & Denmark selected -- these both entries + Congo are selected.
3. Germany & Denmark & United States selected -- these three entries + Congo + Cuba are selected.
4. Aland Islands & Germany & Denmark & United States selected -- these four entries + Cocos (Keeling) Islands + Congo + Cuba are selected.
etc.
Is this only a problem with the display? Or maybe black humour (USA --> Cuba!)
