OctoPrint on TAZ 5 Bed Temperature Drops at Start of Print

I have a new install on a RPI3 B+ running Octopi 0.16.0 and OctoPrint 1.3.10. I have deleted the PLA temperature setting because I do not use PLA at all and preheated the printer to ABS (210/100). As soon as I press print after pre-heating the temperature settings change to 220/60. I have looked for those temperature settings all over the GUI and found nothing.

Here is my terminal output from the time I press print until I cancel:

Hi @Steve_Cline

This is in your gcode:

So OctoPrint can't be the culprit. As @BerndJM said: You may check your slicer settings.

Making those adjustments in the gcode did the trick. There were actually 3 lines of code that reset the temperature. Thanks!
