Return User Error Workflow Condition

I have a workflow that should return an error on work order issuances when a user submits a work order issuance that is backordered. The condition is if the work order (applied to transaction) quantity - quantitycommitted - quantityshiprecv is not 0, and the type of record is a work order issuance, then act return an error before user submit on creation.

For some reason, it is acting on all work order issuances, not just ones that have a backorder on the work order. When I disable to workflow and create a work order issuance with no backorders on the work order, the work order issuance is not populating on my saved search that I am using as criteria.
