Missing sprints in capacity view

I just cannot find the reason why JIRA Portfolio is blanking out a few sprints.

All the sprints are created for future planning, but for some reason it's skipping: 15, 16, 17. It starts again at Sprint 18.

I thought it might potentially have something to do with working days but there's nothing set up for that period.

Any suggestions would be highly appreciated!

Please ignore this question, figured out that there's no versions allocated to that period so nothing could be calculated.
