Source Confusion Between The Transaction and Contribution Fields on a Pledge Payment

I was attempting to check in a payment and originally selected a source, 2021 Unsolicited, then I was prompted that the patron had a pending pledge under a different 1920 source/campaign.  I then selected and processed the pledge payment. Somehow I did not notice that the contribution saved to the correct source on the contribution tab but somehow it saved with the incorrect source in the transaction. Does anyone know how to fix this because my fear is that no matter what I do on the contribution side, it will still incorrectly be listed on the transaction side.
