No worries.. while this was a huge help, this situation was pretty low on my totem pole of "must figure out" items... This was something I could live with, just accept the annoyances.

I tried it the minute I saw this post, and it was great... I just discovered that second step is needed. I tried connecting to the existing valve and the software just looked at me like, "I got nuthin!" haha

Deleted the bolt sets and gasket, after I unpinned everything, and the flange went away....

Left everything pinned, unpinned only the Gasket and Bolt Set, deleted them and the flange stayed put and I was able to connect. when I switch to Construction phase. We have a winner!
