Bed and extruder temp indicator faulty #10

When the print starts, the temps climb properly. Once the print is finished, the temp indicators stay at print temperatures event though the bed and extruder are cooling down. After a print, even when the bed and extruder are completely cold, the temps still indicate 60 and 200. So far three issues on this TFT screen. Not a good start.

I have the same issue with skr mini e3 v1.2 and btt tft35 v2.0....the new firmware V2.0.25.1 solves some problems, but the communication from the board to tft remains buggy. I've found a new bug after the update, it could be very dangerous! My print (which I started from SD card in the TFT) stopped after a time. When I recognized that something is wrong, I saw that the heating temperatures from extruder and bed were at MAX!!! Bed ~100 C and the hotend ~270 C, the printer got stuck and gave full power on heating, i wasn't able to change something over the panel, the whole thing hang up and I switched the printer off...the bed was very hot and it smelled not good...so please beware of using the sd slot and tft for printing. I tested some prints with my onboard lcd and sd slot and had no issues....so please BTT solve this problem, because it can be very dangerous!!!!
