Multileaders with custom blocks

I have created some non-annotative blocks to use with annotative multileader styles. The blocks have an insertion point on the left that the leader attaches to. I select one of these annotative multileader styles, and use it throughout the drawing. Some of the multileaders are drawn to the right and some to the left. They are visually correct to the way I draw them after placing these multileaders into the drawing. The problem happens when I change views, change from model space to paper space, or save the drawing and open the drawing back up. After I do one of these things, the block ends up on the other side of the leader. And sometimes the blocks (not the leaders) end up super small so that I can't even see them. Any ideas how I can keep the blocks on the correct side and to the correct scale that I originally place them?
