Parameter Container not returning superseeding container's value

Hi, I came upon an issue where the value of the volume parameter (possibly others is not returning to the value of the superseeding container's value. In the example below the low volume trumpet starts low then volume is raised by Volup container, but volume remains high after container VolUP ends. I have attached a file. 2.4.0b1

Tried to reproduce from a blank file and things were acting as normal until I extended the loop point on he volume parameter, then parameter got stuck on the sub-container's parameter.
