I did try some hunting around Jim, but the best I could find were PDFs or straight images only. It might be possible to use an image superimposed over the CC2 map you found to correct that one though?

I highlighted the issue of the symbols in this style not snapping to the grid correctly earlier. As that didn't draw a response, and from this topic, it's clearly an ongoing issue, which presumably hasn't been resolved by an update of the Annual more recently.

The structure symbols changing size could be because you changed the size of the symbols while you were mapping, but when you've reopened the file, it's reset to the default size for the area you're mapping (what you get if you click the "Set normal" button after calling up the "Symbol Parameters" information pane).

The structures will actually go on whichever of the Symbols sheets you currently have selected. If you didn't have any of the Symbols sheets selected when you placed the symbol, it will default to the ordinary "Symbols" sheet.

As Sue and Jim have said though, if you are willing to share the FCW file, that should allow us to confirm if anything else may be happening here.

You might be able to use resized pieces of Cosmographer starship gear for the space-stations Jim, if they'll stand resizing sufficiently. At this scale, something that obviously isn't the shape of a planet will probably work!

Also, is it "Disapora"? I don't know Starfinder, but for a scatter of asteroids (which is what this seems to be), "Diaspora" might be more apt.

This looks good.

Not sure about the labels crossing one another though; I'd be inclined to redraft those so they can all be read clearly.

The coastline also seems a bit too harsh and linear currently. Maybe change the land to a smooth-edged polygon, or add some more nodes to the existing coastline, to make it look less jarring - all the other lines flow nicely, after all.

Simplest solution is to use the drop-down menu "List" command by selecting both the overlapping objects, and decide which you need to remove from that information. Make a note of the "Tag #" number.

Close the List window, then click the :CC2ERASE: button (left side column) and click again on the items involved.

Then right click to call up the dialogue box, and choose the "Combine" - "And (Both)" option.

Next, right click again, and choose "More" - "Entity Tag #", and then type in the Tag number for the item you want to delete. This will appear in the Command Line (lower left of the CC3+ window). If the number is correct, press the "Enter" key to accept it, and then right click one last time and choose "Do it". That will remove the chosen one of the two overlapping entities.
