How to get pricing in SBB app for Klein Matterhorn, etal

I am creating a spreadsheet analysis of expected transportation costs to see which pass is best for our trip (List vs Swiss Travel Pass vs Half Fare Pass vs/including Peak2Peak). I CAN find pricing in SBB app for the Gornergrat summit (and associated costs for the Riffelseeweg hike), but I cannot find pricing in the SBB app for the Klein Matterhorn, Furi, and Trockener Steg lifts. I CAN find the lifts in the SBB app, however, when I select "Offers" I receive the message "Connection offers failed" and the "purchase ticket" is grey (ie not selectable). I also went to the matterhornparadise.ch site and could not find the pricing (I did find the Peak2Peak pricing!). Is there something I am doing wrong? I did verify that I am using a valid planning date/time (Wed at 10am). Also, can you help me select which Schwarzsee location I should select on the SBB app. I chose 2 different ones and both sent me to Visp, which is obviously wrong. Finally, in my planning numbers, I compared a 1 day vs 2 day Peak2Peak pricing and found that it is only $22 (list) additional for the second day ($212 vs $234). Am I analyzing this correctly? Your feedback would be greatly appreciated.
