Replace/Add-On ped is invisible

So I’m trying to install this Savitar ped Add-On, but for some reason the ped is invisible.
I already have around 50+ Add-On peds installed and this is my basic setup: Schermopname%20(58)
I just place the files in the stream folder, replace the name in the peds.meta and add the resource to server.cfg
But when I try this with the Savitar (and some other) peds it comes out invisible. The ped files in the stream folder:
Schermopname%20(61) Schermopname%20(60)
I’m pretty sure that it has something to do with replacement files in the latter picture, but I don’t know how to fix this.

Thanks in advance.

What does the resource contain if I may know?
