GuitarTablatures 'N' notes entry mode - Triplets

I have done quick search to see if this bug report has already been reported, but have not found it. If I have missed it, sorry.
Anyway, here it is - when GuitarTabl is already present (being linked to scores staff), when I write notes in NotesEntry mode, using keyboard, and write triplet notes, there seems to be some buggy present. I happened every time I did triplet note entry (writing).
I can only make it look correctly if I first write note which represents triplet duration, then change it to triplet.

See attached file.

Thumbs Up,

Simon
