Recruits locked out due to Playing Time in week 4 of Offseason

On paper this should make sense: by week 4 of the offseason you will have a bunch of recruits officially signed and so any remaining recruits “Playing Time” grade may go down. But what I’m talking about is an incredibly exaggerated and unprovoked drop in grade. I had a transfer QB prospect in my sights and was locked in on him as I only have 1 returning qb and 1 already signed qb recruit but even still 2 qbs is way too low of a number to go into a season with. And all offseason long his playing time was an A-, and this was with the recruit already signed, no other recruits were added or signed on in between weeks 3 and 4 but when I get to week 4 his Playing Time grade had dropped to an F. This happened as well with a HB, guard, and edge rusher (each with varying numbers of players at that position, but still had a massive drop from either a high B or low A all the way to an F after 1 week with no changes) I’m terrified to even advance the week because I know I won’t be able to get my transfers (I can’t spend any hours on them this week since I’m locked out) and I’ll be going into the season with less than the required amount of players at many key positions and forced to take random walk-ons
