Can't select in Dynamic lighting

I am having issues trying to select and delete some dynamic lighting lines in some of my maps. I have noticed some different bug reports along the same subject and I have multiple lines instead of just single lines as I was creating them. The second attachment is in the dungeon that I have in as a map and the first one is a new line I just created and I cannot select that as well. Basically when I try to select them I have selecting a large area instead of just the spots I want to select. The odd thing is some I can and some I can't. Also I will have to say I made a way too small or big of a map depending how you want to say it so the only way to see it well is to be zoomed in at 200%. The last one I created, which is the first picture below to try some different lines is from what I can tell is some I made from lines and some I made from boxes. If I create a box and make it so skinny it looks like a line then I can no longer select them. Please let me know if there is something else I can try to make sure it is not user error. Otherwise people take a look at the map and see what you can see I guess. Thanks.

Please send me a join link, I will take a look at your campaign to see if I can suggest any fixes.

Sent you the link per PM. Let me know if I need to add anything else. Thanks.

Ok, I noticed a couple of issues. First, in your map labelled "Untitled" you have the map shrunk down really small. Even at maximum zoom things are hard to see. If you would like to set it up larger I can show you how. As a reminder: the page size can be increased beyond 25x25. For larger maps (such as this one) the page size should be made to fit the map rather than the map made to fit the page size. Second, regarding the DL lines, you have them as multi-segment lines rather than single-segment lines. That results in a large selection area that makes it hard to select other lines in the same area. This is especially true at zoom levels other than 100% (relates to the first issue). Third, I noticed that some of your DL lines were set to 'thin'. That can also make them harder to select, especially in combination with the second issue. The solution is to make a map that is sized for 100% zoom and to use single-segment lines whenever possible. If you need help with either of these let me know. Edit: I went ahead and duplicated the page and set up a map that is sized for 100% zoom. Your map has a 10' scale but I set the grid to 5' (doubled the size of the map image). It still needs DL lines.

Thanks. I know I made my map too small, however was just weird I still can't select some. I just won't make any maps that small anymore. Thank you for the help.

If you need further help let me know. I can show you how to best set up DL lines if you need.
