WIFI Calling Preferences Being Forced to Cellular Preferred

So here's my problem. I've had poor cellular reception for over a decade at my home, so I had T Mobile  send me a 4G LTE cellspot, which works great.  But with my new 5G phone, it refuses to use 4G and keeps trying to use 5G towers, which no work in my neighborhood. They work very well elsewhere in my city/county, but not at home.  So I've tried to use WiFi calling at home, the phone says it's using it, but it will not connect nor do I get any incoming calls. I have it set to use WiFi and not cellular preferred, it doesn't matter as it always tries using the cellular network. The phone keeps trying to use the 5G towers which suck.  So my only solution is to turn WiFi calling off and manually change my cell service to 4GLTE while at home (so I'm using the cellspot), and then remember to change it back to 5G when I leave the house.

Setting the preferred cell network at home to Automatic (5G on/ 5G/LTE/3G/2G) won’t work either, it won’t use the full bars LTE instead of the nearly non-existent 5G.
