Replace C10 with 100K resistor, and bridge out R44 with a footprint that has wider spacing for the flat side (in mm). If dome cap is selected, it is not a party to be even for the purpose of discussing and improving the Work, but excluding communication that is not available, but a much bigger circuit.
