I recently installed a sensar pro after I was having issues with getting very few channels to come in. I found a bad spot in the coax on the roof coming thru the roof. Once I replaced the whole coax from the antenna to the sensarpro and got everything hooked up I am amazed at the channels I get now!
Hope you can get it figured out.
The OP is talking about specific channels, both on VHF. That effectively eliminates coax and connector issues since everything else is OK. Smells like an avalanche effect that the two channels are barely on the wrong side of and adding another app adds enough noise to kill them.
Although that shouldn't be how it works. Or it's a swamped amp
