Error on Ribbon Button Change

Hi!

I have changed position of a custom ribbon button on quote entity but im getting an error while saving changes(importing Solution into CRM).

I use Visual Ribbon Editor to make changes and i have never had a problem while adding buttons.

I'm sharing error code below.

Thanks for your help.
