Disabled QSL Queue entry for 6Y7EI on 2025-03-14 at 21:02:17 - station location "Williston, Florida" specified in QSO's QTHID item "williston" doesn't match station location "Williston" selected on the QSL Configuration window's LotW tab
Seems like somewhere there is a QTHID "williston," with station location "Williston, Florida" that is accessed when trying to upload to LoTW.
+ Assuming that you changed the name of your LoTW "Station Location" to Williston, as I suggested, then on the Main window's "my QTHs" tab, the LoTW selector in the Entry whose ID is Williston should specify Williston - not "Williston, Florida".
