Details:

I'm trying to finish the old count tier layaway so I can get another package and buy EP but it says "cannot purchase package while another is on layaway" but I only have the one item in my cart. Not sure what it wants me to do.

Error:

cannot purchase package while another is on layaway

Reproduction:

Finishing a count/countess layaway from KS with only 6% left.
