You have a skin placeholder for Foot_R1 and Foot_R1F. What is Foot_R1F? Is that a foot for the female skin? If so, that is not how you want to use skins. Instead you should have a single slot representing the right foot, a skin placeholder which is the placeholder for an attachment that is the right foot that comes from the skin. Like this:
`Foot_R1` slot
`Foot_R1` skin placeholder
`maleskin` skin
`Foot_R1` attachment for the male skin
`femaleskin` skin
`Foot_R1F` attachment for the female skin
You set the Foot_R1 skin placeholder to visible when you want the foot visible, regardless of what skin is active. When the male skin is active the placeholder will have the Foot_R1 attachment. When the female skin is active the placeholder will have the Foot_R1F attachment.
You may want to uncheck Show all skin attachments and look at it, as the skins showing up under the skin placeholders may be adding to the confusion.
