APEX Cloth Mesh invisible on UV Map Change

I’ve got an APEX Cape on my Player Character and use a second UV Map for the Cape-Glide Textures but my Problem is that the Cape Mesh vanishes if I change the UV and use APEX Cloth at the same time. APEX Cloth also gets disabled while Gliding to avoid glitches due to the sometimes high speed.
Is there anything I can do against that vanishing? I’ve created the APEX Asset in 3ds Max.
