Image occlusion: ,, No cloze found on card”

[DivnejAdam]

Hi!
I’ve been using Image occlusion on my Ipad and I just recently started having problems. In some images, Anki goes wild and shows me this.

I am not aware of editing the card, or doing something with it after I created it.
I’ve tried to delete the text of occlusions, as same as deleting the actual yellow boxes that create occlusion, but none of this works.
I do not want to delete the card and redo it, because the schedule of repetition would be lost then.

Any ideas please?

It sounds like you removed one or more occlusions. In the preferences screen, “Empty Cards” should clear it up.
