Grouping creating a mega-group - not separate distinct groups?

[missing string]

Hi there,

So I want to create 5 distinct groups from columns H-AI:

H-L
M-S
T-X
Y-AD
AE-AI

So I create my first group, H-L. However, when I try to create my second group, M-S, it just combines to the two into one big group. I don't ever recall it working this way, could have sworn you could create groups next to each other. I could hack it a bit by inserting a barely visible (or even hidden) column in between each group, but that's not an elegant solution in my opinion. Any fix to this, or has it always been this way and I'm losing my mind?

This happens... Depending if the grouping needs to open to the left or right (right is the default) you need to remember not to select the first column/last column of the group you want to create. Then you'll end up with sub-groups.
Select H-K, apply grouping. It will "include" column L.

I don't ever recall it working this way,

I believe that it did. After all, if you group H:L, where does the group expand/collapse icon (+/-) appear? It appears above column M. It needs to do that since if you collapse the group so that H:L are hidden, you still need to be able to see the expand icon (+) to get those columns to re-appear. Hence column M needs to remain visible. Since column M needs to remain visible it cannot be pert of the next (separate) group otherwise hiding that second group would also hide column M and therefore also hide the expand icon for the first group.
