I though I was the only one. I tend to play simple grooves on upbeat songs. But when we play songs that are a bit slower. Like Clint Brown's, I think CLint Brown, No Word but Holy. I don't know how to play the groove just can't get it. So I just play root as deep as my bass would let me and follow the vocals.
I had just got off that phone with a younger bass player and we talked about the saem things.
The advice I gave him, if you arn't stepping on anyones toes and playing the root on the bottom, then no one could tell you this is wrong.
