Adding a Page or Module to ps_meta table

[akps1234]

Hi there,

I ran into an issue of being unable to disable the left column in the custom module.
I have a custom payment module installed in the PS v.1.6.1.15 and I want to make sure that the left column is not displayed in the module's page.
Usually, it can be done by either through the Advanced settings in the Preferences / Themes / Appearance of Columns or by selecting the Exceptions from the drop-down menu in Modules and Services / Positions.
However, the problem is that the name of the custom module or its pages are not listed in either one.
I tried to add the module description to the ps_meta table in PHPMyAdmin similar to the one like "module-bankwire-payment"
However, it is not showing in the Meta list of Advanced settings in the Preferences / Themes / Appearance of Columns or in the Modules and Services / Positions Exceptions drop-down menu anyway.

Can anyone help with this issue?
