Hi Cliff I tried to replicate the issue.
I am running FW 10.11 on AXE and FW 3.13 on the LF+JR+
So I reset my LF+JR+ and auto synced the LF+ with the AXE ans assigned just 2 I/A's one to drive block 1 and one to amp x/y
I then cycled through the presets and got to my Kurtish preset which I only just setup today (so not a patch from a historical firmware) and I overwrote a default factory preset, so with a brand new preset from scratch I was surprised it happened on this one, I switched through the presets using the preset up function to increment by 1 to swap through my presets, and the axe swtiches into this preset with the amp set to Y, which is not the saved default amp position of X USA Clean.
So I went to the layout on the preset, and only the AMP 1 block is at its Y value.
The other blocks are at the default saved position of X.
I attach the preset here.

The LF+JR+ backup is available on request as i cant upload the 300kB syx file - I backed up the LF+ as soon as the issue occurred.
I also deleted the amp and saved the preset, then added back the same amp block 1 - same issue occurred
I changed the amp type saved, then put back to USA Clean, and stored, and then swapped to the preset from the LF+ and back and again it defaulted to Y not X as stored.
Strange - hope this info helps
