I am getting a similar issue as well, one of my miners is mining RVN but shows MANO in the Miners - Coins column, another miner is mining TUBE but shows XTL in the Miners - Coins column (both are previous coins i mined with those miners).
Awesome Miner Version 5.3.5 (Development preview of 5.4)
Patrike,
There is a weird bug in Miners tab.
Profit mining works well and select the good pool/coin, API access is OK, but reported pool and coin is stuck on an previous pool.
Result is a insane Profit of $12000 for a single gtx 1070

Tell me if you need a screenshot or my xml file
