1Your nozzle set the spool aside
Filafy hides filaments that cannot safely print through your nozzle. The Design step lists them under Excluded filaments.
Fix Use a larger nozzle, or turn off nozzle safety under Settings → Printer.
The spool is a different material
A print never mixes materials, so a PETG spool never joins a PLA print.
Fix Own more than one material? Pick one with Filament material under More options on Setup.
You excluded it
A spool you dragged to Excluded filaments stays out of this conversion.
Fix Click the ✕ on its chip to put it back.

Filafy only uses spools you ticked on My Filaments. A hidden material, brand or type stays out of new conversions.
Fix Check My Filaments and Settings → Filaments.
