Unable to optimize data usage with WFRP module

Hi there!
I play WFRP that, as known, is a HUGE module, 140mb (plus the various official adventures) and that put my data usage above 60%, just for the core modules.

i followed Optimization data usage advice in this topic:

but whenever I import with the summon wizard nothing changes. Still 64% of data usage, stil 140 mb of module.

Am i doing something wrong? I just export with the “Export compendium modules” button, wait for it to finish and then use the Summon Import Wizard to re-import.

If it´s useful this is the console after I try to import with the wizard:



You’re not using the checkbox “Consider a custom Module” when you Import.
