This is definitely bugged.
Official f2 rule is 5 sets of tires. Two harder compounds and 3 softer compounds.
I have the same problem, it occurs often in f2 full career.
In f2 full career you get 5 tires.
I used harder tire in practice and softer tire in qualifying. Harder tire in sprint.
So I used three. And I got the mandatory softer and harder tire left for feature race. But when feature race starts, the strategy only gives you the option of old used tires from sprint and qualifying.
I am not allowed to use the harder and softer tire that was reserved for feature race. I cannot edit the strategy in any significant way. Changing tires is simply not possible.
This is very confusing, because sometimes the bug doesn't occur. For example, silverstone and baku was fine. But in imola, I am not allowed to use the 2 mandatory brand new harder and softter tire that I reserved for the race..
Oh and I have to mention, in the image I shared here, above, the second strategy was identical to this one and also had no possibility to use or switch to the unused medium tires.
I'm not sure if the 3 hard and 2 soft compound race weekend have this bug aswell. But I assume it thus. The bug occurs often.
