Question on verb: ἀποκαλύπτω

Hello! I happened to be looking over the Wiktionary page for this verb and saw they had the aorist rendered as: ἀπεκάλυφᾰ.

https://en.wiktionary.org/wiki/ἀποκαλύπτω#Ancient_Greek

I’m a bit confused, as in my mind it should be ἀπεκάλυψᾰ.

What am I missing?

I’m not sure, but I guess someone might have made a mistake and swapped the letters ψ and φ. In my opinion, it’s incorrect, and the correct form should probably be ἀπεκάλυψα.

Clearly a mistake. I wonder what Textkit’s @ObsequiousNewt is doing now?
