Hello TerenceTCM,
Welcome to Apple Support Communities!
We want to make sure the play count is syncing across your devices using Apple Music.
Let's verify the setting is enabled to share the play count, detailed here:
"Change Sharing preferences in iTunes on PC
In the iTunes app
on your PC, use the Sharing pane of iTunes preferences to share your library (or specific playlists) or choose to update play counts.
To change these preferences, choose Edit > Preferences, then click Sharing."
"Home Sharing computers and devices update play counts
Update play counts (the number of times an item has been played) for items in your iTunes library when the items are played on other computers in your Home Sharing network, or on your iPhone, iPad, or iPod touch.
See Import media using Home Sharing."
This Apple Support page has the full details: Change Sharing preferences in iTunes on PC - Apple Support
If this is already enabled, do you have any pending updates for your devices?
We hope this helps to isolate and resolve the issue causing the play counts to show differently.
Cheers!
