bug: analysis without tablebases

Are there analysis machines without 5-piece tablebases? I get at least two completely wrng comments in a game analysis. In this position
6k1/3r1r2/P2PK3/5p2/8/3Q2P1/5P2/8 w - - 10 85
the move 85.a7 is marked as Blunder but is the best move. It is also not found in the analysis of the 85...Rd8 comment. I also verified that Stockfish without tablebases does not find 85.a7, so I think my diagnosis is correct.

Correct. The analysis engine does not use tablebases.

In endgame positions where the fastest win is outside its horizon, it will make some mistakes like that.

C'est la vie :)
