Topic: Quick Entries 'bal_type' Error Incorrect Integer Value

I've recently updated to version 2.3.1 from 2.2 and now I'm having issues creating new quick entries or updating existing entries.

If I try to make a quick entry with Entry Type of anything other than Journal Entry I get the following error.

DATABASE ERROR : could not insert quick entry for TEST
error code : 1366
error message : Incorrect integer value: '' for column 'bal_type' at row 1

It doesn't seem to be setting the Integer Value to 0 for the 'bal_type'
I've looked at the gl_quick_entries.php file but I can see where it is set.
