Hi.
The epigraphic thesauri works with groups of scripts, and they needs to be set correctly to show grouped into the tools.
First, top of the group needs to be set as Not indexable, because it has not information to set into the legends and is used only for create the group.
for ex:

So, review if your top group is not indexable:

Second. the subgroups and scripts nodes has to be named with the search topic, in this example het as het punic, het neopunic , het punic 1, het punic 2 etc...

and they needs to be marque as Indexable

If all is right you can search and show the scripts into the legends:

I hope it helps, tell me if it works
Best
