When a column is REMOVED, all grouped columns to the right of the removed columns are disrupted. I'll just give a simple example:
  • AdrsBook Grid, sample file.
     
  • Group those four cells : cell, e-mail, leadNbDays, calldate
     
  • Refresh
     
  • Group (collapse) the newly created group.... (visually speaking)
     
  • Right click on the "Lead" column (at the left of the group), remove it (NOT hide)
     
  • The previously created group now contains 5 fields -- 1 that shouldn't be there.
 
AFAICT, the groups needs to be recreated from scratch. It's impossible to fix the disrupted groups without recreating all groups, which is really time consuming in large groups/large grids (with many groups).
 
The only "work around" is to hide columns instead of removing them.
