Changing hole depth drops/changes merge scope

I came across this very odd behavior that feels a lot like a bug so I setup a little test case (see Lighting | Part Studio 2). Simple rectangular extruded part with a thru Hole and a slightly larger concentric partial depth Hole. When I edit the partial depth hole and change the depth, the Merge scope is changed. In the example here, the Merge scope is dropped completely. In these screen shots all I did was change the depth to .8" and hit enter. Boom, the Merge scope got cleared. Notice that indeed the partial depth hole disappears and the feature is in an error state. In another part studio the Merge scope gets changed to a random set of other parts! (took me about half an hour to notice that the scope was being randomly changed!)
It seems that once you then update the scope to be the correct (original) part, you can change the depth as much as you like but if you confirm (or cancel) the change and re-edit the Hole, the same thing happens. It's hard to imagine a scenario in which this would be the desired behavior. Am I missing something? Bug?

So your case is you put two holes coaxially? You drill into nothing the second time? I guess you're creating an invalid boolean condition. Wouldn't a single counterbore hole just do exactly the job? Just asking.

Thanks @martin_kopplow. The larger hole is placed concentric to the smaller hole and seems to work just fine except when you try to change the depth. Then the above odd behavior with randomly changing Merge scopes happens. That just seems like a bug.
As for counterbore, well yes. I didn't think of that as the smaller holes are part of a larger set with only some of them needing counterbore. But yes, that should work and is "the right" approach. I'll just carve off the 8 holes that need to be counterbored.
