Generate ZMK as follows
EC
Key Type: 000
Key Scheme: U
Enter component: 09090909090909090909090909090909
Encrypted Component: U 0A26 760B D078 7102 6B67 02C5 F9BA 25B3
Key check value: D6A8 75

FK
Key length [1,2,3]: 2
Key Type: 000
Key Scheme: U
Component type [X,H,E,S]: E
Enter number of components (2-9): 3
Enter component #1: U0A26760BD07871026B6702C5F9BA25B3
Enter component #2: U0A26760BD07871026B6702C5F9BA25B3

The problem is I expected the check values to match and also the key under lmk for the ZPK to match between the A1 and A7 responses.

Please could you let me know if I am doing something incorrect here?

[Update : works with scheme of ke under ZMK is X.] __

Still curious why the scheme of all U's doesnt work.
