Joint works but it's missing from both viewport and outliner

Hi, so I'm rigging a character and working on the arm's FK/IK switches.

Just to make sure we're on the same page, the way I went making this is I made 3 arms - one for the skin, onr for FK and one for IK, with a switch to decide if its the FK or IK arm the skinned arm will follow. I also wrote an expression to make the arm stretchable in IK mode.

After finishing the left arm and proceeding to the right, I went back to check on the left arm to see if I left any errors I missed on the previous check. Both FK and IK modes work perfectly fine, and even stretchable like it's supposed to.

But the IK joints are missing?

Like, I looked in the outliner, searched in the outliner, went to the display menu and hit show all, nowhere to be seen. I'm certain it's still exists, otherwise the IK handle probably wouldnt work, but I really don't know what's going on here. The pics I attached is the expression I used, the current file and the previous save file respectively. I'll attach my project file too just in case anybody wants to dig into it, I haven't started constraining the right arm yet tho as of writing this.

Update : I found it in a locator's hierarchy. Not entirely sure how the entire thing got there but i'm gonna try pulling it out of the hierarchy and plop it back to the main joints

Update 2 : I guess I must've had the wrong order when I was constraining the stretch's locator, that's why the joints ended up under its hierarchy instead of the main joints
Still odd that it didn't show up when I searched for it in outliner tho, but I'll let it pass now that I've fixed it
