Bambu 4-in-1 PTFE Adapter Tub pops out? Tips?

Hey all, Wondering what you do if you have an Adapter where the bowden tube keeps popping out from the side of 4. Do you put the tube at an angle? Do it differently? I’ve tried a lot of things but can’t seem to figure it out.

I would replace the worn out quick connector or check if the tube in use is not of undersize.
They are not meant to be used for constant changes, the ‘quick’ part just means it is a push in connector that won’t require a screw fitting to hold the tube.

If you can pull the tube out relatively easy from one of the ports while others hold strong you know for sure that a replacement is due.
If this problem kept getting worse over time it is also a clear indicator.
That is of course assuming you have the same problem with new tubes in that connector.
