Go to https://hellosplat.com/s/beanbag/tickets/?status=all

What is the expected output? What do you see instead?
Expected is ticket 4694,4963,4692,4691,4690,4689,4688,4687... no gaps.
Instead, there are gaps in the numbering, e.g. 4626-4678 and 4680-4689 are missing.
Looking at each of these missing numbers under their expected ticket URLs, e.g. https://hellosplat.com/s/beanbag/tickets/4689/ reveals that they are all valid tickets for a project that appears in the dropdown on the listing page, and that should appear in the "All" listing.
They are also missing in other ticket-listing URLs, e.g. "My filed tickets" links me to https://hellosplat.com/s/beanbag/tickets/?status=open&q=reporter:kyz which misses my open tickets 4683,4685 and switching to "All" takes me to https://hellosplat.com/s/beanbag/tickets/?status=all&q=reporter:kyz which misses those opened tickets and also misses closed tickets 4016,4523.
