Hey ,
I did try that last night. At first the child blueprints values are set to 0 and the yellow reset arrow does not appear, but upon changing the value to anything other than 0, I was able to hit the yellow reset button and it did indeed reset to the parent’s value. But the main issue still occurred, whenever I saved, closed the editor and opened it again it would reset the values in the child back to 0. I hope this helps narrow down the issue.
For anyone with a similar issue, a hacky work around I’m using is to manually set any values I was changing in the component on the event Begin Play. Image attached. Thank goodness normal variables aren’t being reset
