Hello,

at first I wanted to report this bug upstream but I noticed that the bug does not appear in their official AppImage, so maybe it's got something to do with how openSUSE ships keepassxc?

## Expected Behavior
After creating a new password, all passwords in the same group are retained.

## Current Behavior
When I create a new password, save the database and then close the database, only the newest password in that group will be available after opening the database again. All other passwords are **lost** (thankfully I noticed this bug in a small group with passwords I can recover easily...).

Anything else accessing the database is disabled (e.g. Nextcloud synchronization and the Firefox keepassxc extension).

I have this behavior in my current database file and in newly created ones as well.

I *think* the bug appeared after I had upgraded to 2.4.3, but I am not sure if I even created a password while being on 2.4.2.

## Steps to Reproduce
1. Create a new database
2. Create two passwords in the Root group
3. Save and close the database
4. Reopen the database. Only the second password will be available.
