If you're using Cura 5.7.2, apparently that has a bug that can cause this, even if your startup gcode should be fine. Try going back to 5.7 or 5.7.1 (you can have as many different versions of Cura as you want installed side by side).
Other than that, IIRC if there aren't lines that heat the hot end to {material_print_temperature_layer_0} and the bed temperature to {material_bed_temperature_layer_0} it will add them automatically to prevent the printer trying to cold extrude or anything bad like that.
If you could post the startup gcode for your printer that would help us diagnose any problems.
And for the love of all things beefy, please no screenshots of text editors. This forum crushes image quality so badly that text becomes unreadable. Click the code button on the toolbar at the top of the edit box and copy + paste your code into that.
