Custom extraction model will not "auto label" table items (line items ). What's causing this?

I noticed in my labeling and model analysis tests the document's table items are not being auto labeled by the model. I can label them manually, for now, but before I did not have to. I only modified the labels the model completed they were incorrect. What could be causing this to fail? Would this malfunction have anything to do with table items not being transcribed in our live production environment? We've noticed an up tick in table items/lines items either being smashed together or not transcribed at all which is causing document errors/manual intervention. Thank you for your help!
