Comma deleted in tags when saving

I just started using Anki. When I create new cards, I always tag them. For about 90% of the cards, after I add a bunch, when I look back at the saved cards there are always two tags put together (one comma removed). I figured out I cannot put spaces in tags and I have to put a comma after the last tag. However, even after making these changes it still happens a lot. Does anyone know how to prevent this? I have to edit most cards after making them to get the tags right. Once I add the comma back in, it stays that way even with the tags exactly the same as when I created them.

I haven’t been able to reproduce the issue. For example, History,of,Mississippi works perfectly fine for me.
