Why does JavaScript Debugger window keep popping up everytime I roll over Stamps>Dynamic, and how can I fix this bug?

In Adobe Acrobat X Standard, I go to Comment>Add stamp(image of person)>Dynamic. As soon as my mouse rolls over Dynamic (without clicking), JavaScript Debugger pops up to show the error message:

"

Acrobat EScript Built-in Functions Version 10.0

Acrobat SOAP 10.0

TypeError: ofield is null

1:Document-Level:AddMessage

"

Only after this occurs, am I able to input my Dynamic DRAFT stamp onto my PDF document.

I wish to fix this bug so that the JavaScript Debugger no longer pops up from simply rolling the mouse over the Dynamic option, so I may directly reach my DRAFT stamp from the Dynamic stamp selection. Everytime the Debugger window pops up, the chain selection of Comment>Add stamp>Dynamic disappears, so I have to run my mouse through the same selection chain (Comment>Add stamp>Dynamic) again in order to reach my DRAFT stamp. Thank you so much!
