Unable to Add Values For Different Options Under the Attributes Tab

With other products in the past, it’s been the case that when I type a value, it turns into a tag after I hit space. Instead, what’s happening with these is that WordPress is thinking they’re all one value, so I’m getting 11” x 14” 13” x 15” 16” x 19” etc all as the same option, instead of them splitting up into separate options. Here are a couple screenshots so you can see what’s happening: https://i.imgur.com/EHQgS2J.jpg
