Data logging in power table using tag historian

Hi there, new user here.
I am trying to create a log table which logs tag value when it changes(using for SP logs).
It perfectly log value when it changes, however there are some tags with quality 200 always logged when opening the window.
How I can create one table which only logs data when value change.

It turns out all the tags with float data type are logging every time I open window. other tags working fine
