Unexpected behavior when add Parallel node before a single sequence

[C's Wonderland]

As the gif shows, the node without parallel soldier can shoot with recoil for each round, but when a parallel node added, the soldier seems lost some recoil, why this happen?

there's a log action before the task SoldierShootEnemy in two cases, both log a text once.

I added this parallel node because I want other sequences run simultaneously, However, I found this unexpected behavior, after investigating, I realized it was caused by adding this node.

These are the BT status related to 2 cases while soldier is shooting:

That shouldn't happen, I'll take a closer look at this and send you the fix.

Alright. Please remember to provide a version compatible with Unity 2022.3.62, as I’m using this version for my personal project.
