Help: DragonTech Aux switches. Can turn off, never turn off

We have DragonTech switches throughout our house that used to work with a HomeSeer control system. The HomeSeer system has been retired and we are attempting to use SmartThings. The master switches work perfectly with the system but we are having an extremely tough time programming the axillary or secondary switch. I am running Smart Lighting and tying the switches together, which allows us to successfully turn on lights from the slave switch, but not turn them off.

Does someone have experience with this and share some assistance.

Thank you!
