Unfortunately, these GE bulbs are not very good zigbee mesh routers. There are ways to get them to work semi-stably, but in general they require some baby-sitting. Most people prefer replacing them with bulbs that work well out of the box (eg. bulbs by Sengled, or Innr). There are also really inexpensive zigbee 3.0 RGBW bulbs made by eWeLink sold under a variety of brand-names that work well with Hubitat. I wrote a review on them a while ago.
