Preset Down / Snapshot Down not working with FS4 / FS 5

[bertha]

I'm trying to set up my HX Stomp so I can do either Preset Up and Down or Snapshot Up and Down from FS 4 and FS 5. I can make either Up (preset or snapshot) work, and they both work on either FS 4 or FS 5. Neither Preset Down nor Snapshot Down will work on either footswitch. 
I just can't make my feet successfully do FS 1 + FS 2 or FS 2 + FS 3, so I need to assign those functions to FS 4 and FS 5.
I have 2 HX Stomps, one is ver 3.11, one is still 2.65, same situation on both. I have 2 external footswitches, both are Mission TT-2s. I've tried both TRS cables and TS Y-cords. Same results with all possible combinations.
Anybody have a solution or a workaround?

Thanks

Put the TT2 in TRS Mode (video on the website). Use a TRS cable.

In Global Settings>Footswitches set FS4/FS5  to Stomp4/Stomp5.

In Global Settings>Preferences set Exp/FS4 to TIP and Exp/FS5 to RING, Tip/Ring Polarity NORMAL.

Use the little gear looking icon on the lower left of the HX Edit screen, Device Settings Tab, to set the functions.

My little $20 Moskey Dual Switch works perfectly for both functions.
