Comments.php updates not working within MyListing theme when this plugin is enabled

Hi there, I have encounted a curious problem – I was updating the comments.php file of the MyListing Child theme to make adjustments to the way that the comments section works, I removed the smiley face.

Comments.php updates not working within MyListing theme when this plugin is enabled, disabling it shows changes

When I disable the MyListing Toolkit plugin the comments.php in the Child file shows the change, however when I activate the plugin it reverts to the original comments.php settings

Is there any reason why this is happening? Thank you
