Running into the same issue.
@jathinhelp how do you accomplish your solution without it getting overwritten in future updates? Adding it where you suggest will get overwritten with any plugin update
That’s the style I was trying to change, but for some reason, nothing will happen when I do so.
Is the code you are referencing found in the add-meta-boxes.php file?
If so, there are multiple instances of that same line of code and I am not sure which to add the title to.
Sorry for my lack of understanding, I tend to excel mostly in design!
