Ah, we use HE here (Hubitat Elevation) for the name of the product. 
You can get 2 way with a community app called OtherHub 2. But for the lights, you don't want to do that. Sengled are the "Safe" bulb to use directly paired with Hubitat because they don't repeat Zigbee signals, so they don't do a crappy job of it like other bulbs that will end up routing and then subsequently dropping your devices.
Pairing them with the HE hub is best. If you still cannot get them to pair, move them closer to the hub. Typically you want to pair in place, but ST radio is quite strong. So where you may not have needed a repeater in the past, you may now require one. IKEA Trådfri outlets are good at repeating not only compliant Zigbee, but also non-compliant Xiaomi devices and they're inexpensive. They also have a dedicated repeater. Were talking $10 for the Outlet and $12 for the dedicated repeater which can also run off a 5v USB connection. I should add that while they happily seem to repeat just about everything, they're not that strong, so if your house is big, get a couple of them.
