No start and end code in Cura for Ultimaker S5

[monstrum 0]

After installing Cura and setting up the Ultimaker S5, we notice some problems with start and end procedure. At start, some small blobs are present in the part area which does not seem to interfere with the printing, however, it leaves some brownish blobs of material in the first layer (printing white PLA). When the print finishes, the printer just stops and cools down on the spot, leaving a blob on the part. This could probably be solved by better priming of the nozzle before printing.

I noticed the start and end gcode in machine settings are blank. Is it at alla handled (maybe in firmware), is it missing or is it just supposed to be like this?

Adding some code to the end script to retract and move away from the part would probably solve it but I considering everything should be plug-n-play for this setup, I don't want to spend time tinkering unless it is absolutely necessary.
