Text field doesn't appear right on button rollovers

I’m not sure what I’m doing wrong, or what to search for here, but here goes.

I have 5 buttons which all populate a dynamic text field with a variable, on rollover.

When any of the buttons are clicked, the rollovers don’t populate the dynamic text field anymore.

I tried adding AS to enable the buttons again and that didn’t work (button.enabled = true)

Any other ideas? What would cause the rollover state (populating my dynamic text field) to stop working?
