People who made filters in G'MIC might want to rename them for multiple reasons and they are free to do it.
The first reason which come in my mind is because they added more functionalities to their filter, de-facto the original filter do a lot more than the original naming, thus they rename it

other than trying the 1122 filters to find it back under a new name... (yes 1122 filters >
https://gmic.eu/gui_filters , the Testing group (+>550) is not taken in count when you see 569 filters)
EDIT,
to not "lose" a filter in the future, it's a good idea to keep your favorite filters in your "Faves", right click on a filter > add to faves, once in your faves, you can even rename them, right click on the filter in your Faves > rename
