When I try to create a multileader style with a user block, I can select the block I want to use, but it doesn't seem to recognize it. In the preview as well as any multileaders that I create it just shows an empty square. If I go back later and try to edit the multileader style it shows "detail callout" as the block. It's like it never accepted that block in the first place. I've tried with many different blocks, always with the same results. I made sure that the blocks I'm choosing are not annotative, also. If I edit a multileader individually after it's drawn, I can put in the user block I want, and it shows up fine. Does anyone know what's going on?
