Undo samples in Rec Mode with Trig Mode set to Slots


I have Trig Mode set to Slots in Rec Mode to trigger samples which works fine in live recording. But how do I go about undoing the most recently added sample to slot playback when it doesn’t work?
I cannot find the answer in the manual or in these forums. Thanks in advance.

Do you mean change the Sample Lock for a particular Trig in the sequence ?

If you want to change the sample that was recorded to a particular Trig, then in Rec mode, hold down the Trig and you can scroll through the locked Sample list with the Level encoder
