Engine bug? Why this values are automatically being set back to the default

Hey guys! Whenever i restart the engine, all this values that i set in childs BP of an actor that has this struct is beeing desapearing. I mean, if i set a value and restart the engine, is like i doesn’t do nothing. This started when i added the last integer to the struct. I have github in the project, so if there is a way to back in some point in the progress i can do it. Can someone help please?
