Dimension Tool works once unless I reselect a scene

So my dimension tool has been on the fritz ever since I updated sketch up the last time.

  1. The dimension tool only works once sometimes unless I reset the scene at the top of the page.
  2. Sometimes I will put them on a tagged layer and turn it off, then come back to the tagged layer later only to find they have all disappeared. Checking all hidden objects as well as all other tags, they are no where to be found.

I make sure to always keep the dimensions out of the group.

I have checked that the expert dimension hide toggles are OFF.

Please share the file that shows this behaviour.
