No custom properities in the sidebar any more

[mzed2k]

Hello,

thank you for implementing the new features. I've just upgraded from version 1.01 (?) to version 2.0. Now the sidebar doesn't show the custom properties tab any more.
My existing properties (e.g. "md5") have been converted, but they don't seem to be fit for the new requirements.
I've deleted them and added a new one, but no success.

NC Version: 20.0.10.1
(Ubuntu, Apache, MySQL 5.7.34, PHP 7.4.15)

Any ideas?
Thanks,
Martin
