Unwanted tab movements in styles

[Alarix]

I have a headache with unwanted movements of tabulators in user created styles. I wanted to attach a short .avi video of this (29Mb), but this is not possible due to lacking security tags.
So in words it goes this way:
At the second instance of alphanumeric numbering (a), b), c)) I want to restart numbering from a), as it starts at d). So I right click, restart from a is the command, the points are renumbered, but the a) point jumps to the right by about one tab. When I move the paragraph back and do the "Update the style xy to match the selection", the numbering jumps back to d), and the vicious circle can start again. :-)


Any help or solution? I will mail the video but have to figure out how.
