The most probably this is because of improper using of methods

BeginUndoGroup and SetUndoGroupMode.

It's very important to follow the rules:

1) Each call of SetUndoGroupMode(True) must have the corresponding call of

SetUndoGroupMode(False). If these calls will not be in pairs, undo will not

work properly

2) Each call of SetUndoGroupMode(True) must be preceded by the call of

BeginUndoGroup

3) Typing cannot be grouped

4) There are some limitations on grouping actions in different cell inplace

editors.
