In case anybody else stumbles in here looking for the same thing, here are some good options I came across with different artistic styles and angles.

I figured it out, I was forgetting to check the box on the far left when changing the sheet to the "Text Sheet" to confirm the change. Derp, lol, live and learn. Thanks for the help.

I don't see how it could be hidden by anything, the location I'm attempting this at only has the Land under it. I had already gone as far as hiding all layers but the text still disappeared.

I did see it become highlighted while "pretending to delete" but when going through the change properties menu, it says it is on the text sheet already.

The sheets should be in the correct order since I have not made any adjustments since starting the map, for the exception of the hand drawn image I had scanned and imported for the base construction of the landmasses and general placement of settlements, mountains, forests, etc. which I hide when not needed.

EDIT: Ok, I don't know what I did differently on my 10th attempt but it is working now, lol.

I didn't realize you could create your own symbols. If that's the case, I could find some placeholders for now. I'm a seasoned photoshop user due to the nature of my job so I could always create a png from some fantasy style artwork if need be.

I just really enjoy working with the style of the Mike Schley collection of symbols so I'll find something for now and keep my fingers crossed for the addition of more Oriental themed symbols to accompany the Oriental buildings already available.

Oh yeah, and the download for this month's free content does include June's content as well. Both the Elven buildings and Orcish buildings are installed using the MCJuly2021 update file, which is very convenient might I add since I would have missed out on the Elven buildings (which I REALLY needed for my map). In fact, I even added an Orcish territory to my map that I had no plans on making because of the new monthly symbols, lol.

I only said that because I've seen people get all iffy about stuff like that before. But hey, we are making maps for fantasy worlds were dragons and elves exist. Nothing needs to make complete sense, right?
