Bugged training medals

[Bydofied]

These medals didn't unlock for me, and I'm sure I completed the requirements:

4-2: Clear in 15 seconds
4-3: Clear in 15 seconds
5-7: No damage for 10 seconds
5-8: Clear without overheat
6-9: Clear in 20 seconds

Also the 6-7 medal: Clear with 5 or fewer boosts didn't unlock when I used 4 but I got it when I didn't use any.

You can still get the weapons, but you won't be able to complete the 180 tasks and earn the training medal.
