Instruments not showing on GarageBand

[niarmc]

Hi there,

I've installed the MSF instruments quite a few times and MSF doesn't seem to add them in the tool.
Mdrummer works like a charm and detects all the instruments downloaded and installed (which can be seen below.
The point is that MSF don't detect the instruments at all, none of them. I've installed the plugging a few times, version 14 and 15 (currently 15), and reinstalled the instruments like 6 times already.
Restarted the MacBook, etc.

GarageBand finds the plugins with no issues and so far I can use all of them. the only issue found is the library of instruments for MSF.

Please, can you help me?
Thank you in advance.
