You need to use a big enough Negative solder mask expansion and big enough Negative paste mask expansion. You can also use the option Force complete tenting on top/bottom for the particular pads to make them covered with solder mask. Make sure that in the PCB you don't have any rules which over-ride/re-define the expansion values. Also try setting the expansion values manually for the net ties in the PCB again, to see if that fixes the problem. If you go to the Paste and Solder layers and switch to single layer mode, you shouldn't see any paste/solder mask over the net tie footprint.
