In attached file there are two parts set up for sequential printing.
The processes are essentially the same and both have First layer bed temperatures of 102C and subsequent layers at 85C (btw the filament is ColorFabb nGen (not XT as in profile name)).
The gcode generated for the first part is of the form:
M190 S102 (to wait for bed temperature to be achieved).
However when it comes to the second part there is only:
What that means, of course, is that the printer will start the second part whilst the bed is still only at 85C and the first layer will not be printed under the intended conditions.
I think this is an oversight and in the case of the sequential printing of parts we need an M190 as well.
