BUG - Uninstall/Reinstall the same package

The problem:
After reinstall ‘insert-timestampv0.2.4, the command “insert-timestamp:DateT” will insert multiple instance of the time stamp.

for example, after uninstall and reinstall the same package 4 times, when I insert the time stamp, it will create multiple instance of the same timestamp in a single line like so:

4/29/2021, 10:56:39 AM4/29/2021, 10:56:39 AM4/29/2021, 10:56:39 AM4/29/2021, 10:56:39 AM
