Transferring journals, rolltables, playlists between worlds with different system

Hello. So my problem is, I tried to create a custom module using the shared compendium, but when I entered my new world with a different system, the compendiums that I want appears, but it is blank when I click it or try to import them. The folder appears and I can unlock them, but they continue to be blank and empty, and when I try to import it shows that 0 items have been transferred and the folder is blank. Is there any way that I can make this work with a different system between the two worlds?

Did you use our shared compendium feature or tried to create a custom module yourself using some online guide ?

Tried to use the share compendium feature, yes.
