Model view bugs

Hi all,

The data model for one of my files has gone haywire. When I first open it no connections are visible. If I move fact tables around, the connections suddenly appear, odd. One of my fact tables I recently added can’t be moved and when i click it the expand/collapse the views go weird:

If I move my dim tables the connections don’t move with them:

This is only affecting one of my files. I upgraded to the July PBI version, don’t know if it’s related but it happened after the upgrade.

Any idea how to solve?

Thanks,
Tim
