Backup from Unraid to Synology - File Modified Date Changing

Hello, I am new to Unraid and so far have been enjoying my experience. I am running into a problem and am hoping someone can help me. I have my unraid box and a synology box. I created an SMB share on the synology and am using the "Unattached Devices" plugin to mount the share to the unraid server. I then have a FreeFileSync docker container that I am using to copy the files(Mirror) from the Unraid box to the Synology Box. The problem I am having is that everytime I run a compare to see changes that need to sync all the same files keep re-appearing. From what I can tell the modified date keeps changing on the files.

I have a Windows machine that I mounted my unraid share and synology share on and am using freefilesync there to do the mirror/copy and things are working as expected. The modified date doesnt change when I run a compare the same files do not reappear.

This is driving me nuts and I can't figure out what the problem may be.

Thank you for any help
