Usually when I am going through my new kanji lessons on WK, I will see both (or multiple) on’yomi and kun’yomi readings listed, though one set is usually greyed out since it is not the reading that WK has chosen to emphasize in that level/lesson. But for some reason I thought that WK still included all the known readings.
I just reached the kanji for “borrow”:

and I noticed that it uses 昔 (long ago) as its phonetic component and takes the せき reading. I thought it was odd that I didn’t remember this reading, so I checked in Level 11 and sure enough せき isn’t listed.
Has this always been the case and I just misunderstood? Does WK only includes the readings that it teaches in other kanji or vocab? Thanks!
