There is an odd occasional behaviour with tyre wear in Quali.
After using first set of Softs in Q1, there are not shown as used in Q2.
First set is still displayed as never used although I ran five laps on them in Q1.
After Q2, tyre wear is preserved in Q3.
I noticed this behaviour mostly in weekends with sprint races but I could not always reproduce it.
