I had a somewhat similar issue. My Kaga had equipped Type 0 FM 21 Skilled, Reppuu (601 AG), Tenzan Tomonaga, and another 21 Skilled (plane slots in this order). I used her in pvp only as well, but never lost many planes, I watched out for this. The first 3 planes had double chevron ranks, the last skilled fighter was on level 1 (this one was on lv1 for at least one week, and I don't know why). But one day (I believe it was this week's Monday) in the morning the ranks were just like these, in the evening suddenly The first 3 planes had their ranks reduced to 2-1-2 respectively, meanwhile the previously lv1 fighter became lv7. On the next morning, all planes (except the lv7 one) became lv1 planes.

I'm also interested in some kind of explanation, because there's no way I got my plane squads wiped without noticing it (meanwhile the 12 slot fighter got to the max).
