Game not showing in library

Have the prodkeys updated, the Firmware is 20.1.1 (not the most recent but not old by any means). So I am having this issua with 2 roms FE Three Hopes and 13 sentinels, the weird thing is that I can play Unicorn Overlord wich is a more recent game and not only shows in the library but it works fine, I have tried to look for a answer in the internet but couldnt find anything that helped. So what gives?
