Strange behaviour of the Elements WIndow

Hi everybody, my Elements window sometimes behaves in a very strange way, all the numbers at the left (circled in red in the picture) disappear, this is a problem because I cannot copy, remove many items, renumber ecc.ecc.
I couldn't find a logical answer. For some file happens even if I restart the whole system, but it doesn't happen always for a single file.
I use windows XP SP2 and Caesar II 5.10.
Many thanks

Hello,

I had that issue, you just have to expand those cells.

... and if you can't do that, then delete the ".grd" file for that particular job.
