When using the Delay Calculator's default template, you must make sure you select an option for all three parameters. I have updated it to calculate a standard delay by default instead of forcing you to choose one which may have been the issue you were running into. For the Reverb Calculator, I cannot replicate this issue. Could you send me a screen recording of what happens when you try running the script please.
