Default settings stays on 0 or not visible

Hi,

I'm using PHPStorm version 2018.3 and have difficulties with the default settings in Database. The data source I'm using is MySQL. When I create or modify the default value of a table, it's not visible or get wrong value. Mostly it's 0 (zero). For example: I set default value of 'online_datum' and it stays on 0 instead of the value I gave.

When I check the database structure in MySql Workbench, the settings are correct but in PHPStorm the default value stays on 0. I already invalidated caches and restarted, synchronized DB but nothing changes.

How can I solve this issue?

With kinds regards, Erkan
