Grouping PC devices for insert/replace Problematic?

...or is it me?

It seems that sometimes when I perform this operation, it works and other times it doesn't...?

Example...

I decide to add a Console Emulation Channel to all of my drums tracks...

So I select all the drum tracks and then hold down Ctrl while preceding with the module selection process... Often it doesn't work... It may be something I'm doing wrong but I seem to miss noticing what that may be...

Once I've inserted them I can ctrl-adjust all the selected tracks simultaneously... that seems to work all the time...

So what might I be intermittent in my process/thinking?

Thanks for any thoughts...

One thing I wonder is don't select all tracks just the one and use ctrl plus the module to insert.
