Error while restoring an additional database. A bit value of '0' restores to '1'

This occured in a database added with "Muliple Database Definitions"

An illustration of the problem is in the second attachment.(pdf)

MariaDB Versions:
Source-Server: 10.6.18-MariaDB-0ubuntu0.22.04.1 - Ubuntu 22.04
Destinaltion-Server: 10.4.32-MariaDB - Source distribution 

Both protocol-versions are: 10

Akeeba Kickstart Professional 8.0.6 was used for the restore.

This issue is problematic, because it happens completely silent.

Thankyou for having a look.

See https://stackoverflow.com/questions/8778906/fetching-bit-field-with-mysql-query for a bit more context.

The problem is that BIT fields are not supported natively in PHP. The database server returns a string, not a number, or array of booleans you'd probably expect. They need all sorts of explicit casting both to read from, and write into them.

Adding support for BIT fields would require making the database backup about 25% slower for everybody. At the same time, you are the only person who tried using a BIT field in the past 18 years. Therefore, it makes no business sense degrading the experience on hundreds thousands of backups each day just for this one site. It would make far more sense for you to use a TINYINT instead.
