Issues with map name and map display name

[Sambari]

I've been trying for the past 10 minutes to save a map that I'm creating, but no matter what I put, it says that the map name is invalid. What exactly do I need for map name and map display name? I've made a map before plenty fine, but I just have no idea what is wrong with naming this one. I've tried naming the display name like ExampleExample and Example.png and such, and with the display name it has been like Example Example and Example Example.png just to test out if the .png would work on it, but nothing seems to be working whatsoever. Help?

The map name needs to not have any spaces in it. Like this: Exampleexample. For the display name it can have spaces. It's picky like that. But if that doesn't work, post another and I shall see what the problem is.

[Ingredient]

The Map Name cannot use spaces or symbols such as ./,!~ and etc. There may accidentally be a space at the end of the name.

For the Display Name spaces and symbols are allowed so it must be the Map Name causing the problem.

I still can't get it to work. Here's a screenshot of what I put.

Re-start Feralheart and try saving the map BEFORE adding the map terrain and mask. Sometimes it works for me.
