Can't access singleton Variable


I have successfully set a Singleton and in my main menu level BP I created a reference and successfully was able to see my variables and get them with no errors. When I print these variables however any default numerical values for float or int is 0 always and any string is just blank. I tried to set it up so one of those variables was a master volume that I access at startup for the main menu music, I have it set to a settings slider and the slider is stuck at zero also.
