Everyday 2 shirt morphs for sleeves?

RenderPretender

Hello -

I am trying to use Aeon Soul's Everyday 2 and its add-on, Morphs+. The products have two shirts... a full length one and a short one. The full length shirt has a "Sleeves Up" morph, but the midriff shirt does not appear to have it. I'm mystified as to why two generally identical (save for length) shirts don't both offer the "Sleeves Up" morph, especially given the cost of these products. Is there a remedy for this, such as somehow transferring the morph from the long shirt to the short one?

Thanks!
