Adaptive_selection missing nodes

Hello,

I have a cluster with 3 master nodes, 2 coordinator nodes, and 4 data nodes. Of the 4 data nodes, only 2 of them are showing up in the adaptive_selection of node stats. Because of this, only those 2 nodes are performing queries. I have tried disabling ARS, but that doesnt seem to change anything. Does anyone have any ideas or suggestions on how to get the other 2 nodes to show up and start performing queries?
