No it doesn't.
Why do you think it proves any such thing?
It isn't even a strong indicator towards that IMO.
BTW, the top screenshot, showing the two #38 bases doesn't show a significant level of mismatch IMO.
It happens. It is rare - the comments on here may be quite frequent, but that is the nature of this sort of forum, you hear about the exceptions, not about the many times that number which are the norm.
Clans are being matched with much stronger or weaker clans.
It's time Supercell acknowledge this and fix it soon.
Our clan has fought a total of 101 wars - 51 of those at 25v25, a few at 30v30, most of the rest at 20v20. In that time, we have had a few overwhelming victories, but only 2-3 altogether where there was a serious mismatch (either way) looking at the bases. The overwhelming victories were mainly because they didn't attack well and/or didn't use a lot of their attacks.
Mismatches do happen, and I think they are exacerbated by particular sizes and TH mixes in the clan - the more unusual the combination of size and TH mix, then the more likely a mismatch is.
But I don't think they are common enough overall to be able to say there is a bug.
