HR24 700 adding to Slimline 3 SWM with splitter not working

I have a slimline 3 SWM dish at our remote cabin.  I’m trying to add a HR24-700 to the dish using a SWM splitter to get TV in our second bedroom.   I put the splitter between the dish and SWM power unit and then connected the dish to the second output on the splitter, not the pass through power side.  The main receiver is working fine.  The HR24 dish setup is slimline 3 with multi switch type.  It was working this way for a few hours until I accidentally turned the power off at the power strip.  If I change the receiver to SWM switch type then I get a drop in signal strength with a bunch of transponders showing 0, multi switch type shows signal of all 91 and high 80s except for transponder 24 which shows 0.  The main receiver shows same signal strength and shows 89 for transponder 24. I even swapped the receiver position and it still shows a 0 on transponder 24 and still can’t get the HR24 to complete the dish setup.   It shows a warning of need a B-band converter on the dish setup, not sure if I need one. I still also have an old 18” round dish that I am using and trying to switch to the newer slimline 3, and the HR24 still is working on that dish.  At my main residence this HR24 is connected and working on a slimline3 SWM setup, just not when I’m taking to our remote cabin for the week.
