Number of cards in a filtered deck differs between mobile and desktop app after sync

I’m not sure if I should place this here or in the mobile app section.
When I rebuilt a filtered deck on my iPhone and then synced my desktop I got different numbers of cards in that deck.
After rebuilding the deck in a desktop app I got the same number as I had in mobile. But shouldn’t they be the same after sync?

Both apps in the latest official versions

Same issues here
