Transactions form - Balance Due form is showing tax amount as credited

When crediting an Invoice taxed using Vertex 'Q' series in full that contains 3 tax lines, the  tax amount is not being credited and the invoice is remaining open for the tax amount. However, in the AR Transactions form the Balance Due form is showing the tax amount as being credited. However, the form is also correctly showing the invoice is still open by the amount of the tax.

Is this an issue with Transactions Form?

We are creating the Credit using Vertex O series.
