Noticed there is customer/project in the customer field. Any idea how to get rid of in bulk?

So you have AR line on JE without name .. So you need to modify all JE to put a name otherwise you have to reclassify this AP account without name to the same AP account with name in a new JE

All different accounting periods. Ranging from 21-24

if it's historical JE that doesn't matter to you then you can customize and add a filter by removing the no customers in your report

Great! Where would I go to do this?

Customize on your report

Got it! Thanks!
