Out of Sync - generic error between Unraid and Synology

I’ve got Syncthing transfering data one way from my Unraid server to a Synology Diskstation. My initial sync worked ok. However, after some time I started getting an Out of Sync message on the Synology Diskstation on one of the files.

On the Diskstation I now have two files of 1760957 kb. One named .syncthing.2_CyberLinke_PowerDirector11_ContentPack_Essential_G5_PCP120712-02.exe.tmp and the original file (that I manually copied over trying to get it to get it to consider it sync’d).

Looking for any insight on what I should do next. Appreciate any guidance.

I turned on model logging on both sides and I’m pasting the relevant pieces below:
