Pipeline Steps are sometimes hidden/nested when bulk editing

When I want to bulk edit fields in my asset list (ie “Edit Selected”), sometimes the pipeline steps are nested under other steps. You can see in the images attached: one is the ideal where are all the pipeline steps are listed, and the other shows how the remaining steps are nested under “Phase 02” and not shown unless I have the dropdown open. Sometimes fields are nested multiple times over and are annoying to find.

This problem seems to be connected to how many fields are included on a page. The more columns I add, the worse the nesting gets. Is this a bug, or do I just need to limit how many fields I have displayed on any one page?
