Story views coming up as two different numbers?

Hey there, just a quick question. I’ve got an account with just over 100k followers. And the last couple of weeks, I’ve noticed that sometimes when I post on there, I’ll get two different numbers telling me how many people have seen it, such as this one. One thing is saying I’ve got 86 views, then below it says I’ve got 69. I’ve cleared cache, deleted the app, logged out and then back in and it stays the same. Any idea’s why this is?

Thanks!
