Formatting problem with dive list following delete dive from grouped table

[Willem Ferguson]

I delete a file from a AUTOGROUPED dive list. See:

Upon deletion, the dive list becomes damaged. This is the result:

After some experimenting with this table and expanding some of the 
columns, here is the result:

Notice the second column containing the numbers of dives is organised 
totally differently. The colums that were not initially present in the 
group headings now apply also to the group headings. In general the 
table is a bit screwed.

Would this be something easy to fix?
Kind regards,
