Just in case here is a reproducible step by step.
- Power on
- Load Alex Ball Budget Digital kit
- Go to Bank B. Pad 1 is blue
- Shift+track
- Move/Copy track
- From Track B1 to Track B2
- Copy&Overwrite
- GO
→ Pad 2 is red
Bonus bug in step 6.
In the “Move/Copy Track” window pressing a pad makes the cursor go down to the next line.
