Single Click versus Double Click Action not working

Hello, having an issue with actions on symbols.

I have symbols that when clicked play at a specific location on the timeline.

Tthe first symbol uses single click (how I want it)

The rest of the symbols also use single click, but when I test the animation they require double click (even though they are coded to be single click)

Any ideas?

Here is a testing location for the animation:

Ideally I want single click on all the symbols. The double click is confusing.

Thanks!
