Russ,
I'm not seeing it in any of these examples, sorry. The top extrusions ( VAM 6 and 8) are usually obvious at that magnification. I also don't see the "check-mark" on any of these.
For the benefit of others, here's one of your shots with an overlay of the '7'. The bolded red is the "check-mark" we look for.
