In CAT 4.6 there seems to be a bug, in BTC markets at least, where an old order keeps getting reloaded as a new one during every refresh:
Not sure to have understand what the problem is. If you have a log please send me.
EDIT: taking a fast look at your logs there's a moment where CAT stop making actions (at the end of market log) but your 85 USDT seems legit. Gain on this market is in USDT not BTC.
The $85 is definitely incorrect. I checked and the profit is only $0.28. The cumulative sum $85 is because the same orders keep getting loaded back into CAT every 40 s.
Loaded back from where? It's very strange because nobody ever had this kind of problem with CAT 4.6
