When using buttons and having them link to a tab that shares a similar name with another, it will open both. My test case was opening Plex (in a new tab) and when it would open it, it would open PlexPy (in an iFrame). Change the PlexPy tab to "Stats" fixed it so you may want to look into stricter word matching logic.
For reference, my tabs were named Plex & PlexPy when I was having the issue. Plex & Stats when it works fine.
