Nope, not the only one but I'd not spotted your earlier post. I actually managed to get a screenshot of this yesterday, but I'm still trying to work out if there's any pattern.
Here's my screenshot, and in it you can see that Shadowheart is the currently active character in combat, and has shared initiative with Wyll, but the next two characters in the order are greyed out as they for some reason had their turns before Shadowheart and Wyll.
Also, normally, if there's a tie between some of PCs, it's up to the player to decide the order between them. The DM only order ties between NPC and NPC/PC.
