You might do this for example if you lost your Driver tag, you would screw in another tag such as the X1 into your Driver grip and you would remove the Driver from the D tag slot and re-assign it to the X1 tag slot in your My Bag.
To remove a club on your mobile device please follow these instructions:
1) Login to your app.
2) Navigate to the My Bag screen on the app.
3) Tap on the club you wish to remove from that slot. Then tap on "Remove" at the bottom of the screen.
4 Tap "accept" on the pop up box to confirm this removal.
This will now remove that club from that tag slot. You are now able to add another club to this slot and re-assign your initial club to another slot if you wish.
