infographic designer error

Hello,

I'm experimenting an issue importing custom visual infographic designers.

When import it in the visual pannel of power bi desktop occurred the errors below:

• sometimes appear this error:



• when i right click on the sheet i can't see the drop down list:



• when i try to import a new custom visual i can't see the drop down list:



• I can't expand a drop down list in the setting panel of the infographic designer visual:



The errors above occurred only when i import the infographic designer visual.

thank everybody...
