Custom Client Side Formatter Getting Evaluated 4 Times

Wappler Version : 4.6.2
Operating System : W10
Server Model: NodeJS

Expected behavior

Any custom formatter, called on say click of a button, should evaluate the expression just once.

Actual behavior

The custom formatter is getting executed 4 times - consistently.

How to reproduce

Not sure if this can be reproduced.
I created a formatter and added console log in it. Called the formatter on button click, and no where else on the projecct.
Now, when I click the button, I can see 4 logs in console.
I have never seen this behaviour before, so maybe something has changed? Please help.
