Brew4me - I looked at the Stone Pale Ale recipe(s) at their site, but your BIABacus file didn't appear on your post.
I trust that you have your kettle dimensions entered at the start; make sure the VIF volume target is filled in (Section B), enter the grain weights they gave and the hops with their AA% and times (blank=pellets for the form on left side of Sections C & D). and watch for the right side of the grains and hops entries (Sections C & D) to get populated.
Their recipe says "about 9 gallons" for what I think is TWN (total water needed) but you may get a smaller number of gallons in Section K to go with altered grain and hops weights (Sections C & D) that will all fit in your kettle - watch the Mash volume field in Section K (and red warnings appear atop Sections A & B if you go too big). Tinker with the VIF to fit.
Even before seeing your BIABacus file, I'd say their strike water temp is higher than ideal. I believe it is better to let the ambient temperature grains lower the (strike) water temp a smaller number of degrees and then stir while applying heat to get back to the target mash temp. Also, BIAB will have all
the water in the kettle at the time you start adding grains to your bag lining the kettle.
Try posting your file again, and good luck.
