What is see is not perfect but expected. If I understand the video correctly. I just checked the source data and the first leg of SID BEVVR1 for example really says: Fly heading 206 until at 7100 ft. 
I could tune the depiction and add curves, though.
BTW: LNM does not care about the Navigraph update in MSFS except for airports, COM and ILS. The procedures come from the Navigraph database in LNM and not from MSFS. What you see is independent of the beta navdata update 13. You can read here in chapter Navigation Databases about what is coming from where depending on selection in the scenery library menu.
Sorry, known issue. I’m aware that this is annoying but I have no idea how to fix it since it is a problem with a library I’m using (Qt). I already spend days trying to workaround all these dock window issues.
Options:
- You can disallow map window undocking in options on page
Map. This will limit the dock window positions but stop the behavior you show in the video. - Move the elevation profile to another position into the corners or below the map. Then you can resize it again. Save the layout if you have it as needed.
