I've discovered two grid squares between sectors (not part of any sector, according to the Nav coordinates). Is that something I should write a ticket about, or is that a fairly common occurrence? They should be part of Senex, I think, as both sit on the border of Senex, and the shape of Senex and the adjacent system would be changed if either were made a part of the adjacent system.

It does happen, The sector borders aren't perfect and there are gaps between many of them.

As well the bulk of the left side of the map has no sector.

It's only an issue if I try and put a populated system there with no container. Empty space is perfectly fine and normal outside.

Thanks!
