iClone animation to Marvelous Designer

Hello, I am having an issue exporting animations to Marvelous Designer via Auto Convert to Motion. FBX files from Mixamo import without any problems, but when exporting from iClone, I receive the following message:

What settings should I use when exporting FBX from iClone/CC?

When I export a character animation from iclone to marvelous designer, i export it as an alembic. Then just make the first 1-10 frames are the character in t-pose or a-pose, so you can easily fit the clothes in.
