Field Names Changing After Refresh

I have a PBIX file where suddenly just refreshing the dataset seems to be breaking my column renames. In Power Query, I'm using Table.RenameColumns to change the Dataverse source columns to more human friendly names. This was working fine, but when I click the refresh button today, some, but not all of the columns change to names I didn't specify. In some cases, it seems to be reverting to the display name from Dataverse, in other cases the logical name and in the remaining cases, it stays the same. Does anyone have any idea what is going on?
