Yes, I did not want to say, it’s not a problem, or marginalize it, sorry if it looks like,..
I do some web development and quiet often those filter on “datatables” like this one are using only data that are inside “datatables”. So if full name is not print inside, filter cant find it.
Maybe this is not this case, datatable can be server-side filtered, if it works before and full name was not visible.
Either way i believe github issues are the right place to raise bug report for this.
