Screenshots not coming through?

[Kraken Guard]

I've been trying to take screenshots of Jolly Roger, but i've noticed most of them aren't coming through (Some of them do, just not all of them.) And im not sure if this is a glitch or if they reduced the amount of screenshots your aloud to take.

I've been tapping F9 repeatedly and i get the little message saying screenshot taken or whatever it says. I go to look in the screenshot folder but there are no screenshots found.

Any tips?
