Bug with 'Insert table' from ribbon with multiple displays.
When having two documents open. One on my laptop screen, one on my secondary display. I select table-> insert table from the ribbon from the document on the secondary display.
The table dialog pops-up on the laptop display, and when pressing OK the table is inserted in the document on the laptop display.
This is Word for Mac version 15.37 (170815) by the way.
The same bug when using the Insert or Table menu.
