Cannot create price set with auto-renewing memberships

When I try to create a price set with memberships that auto-renew, an error pops up when I try to save the price field saying:
'You can include auto-renew membership choices for only one price field in a price set. Another field in this set already contains one or more auto-renew membership options.'

I've replicated this problem on the 4.7.2 sandbox site. The steps I took are:
1. Create a membership type with optional or required Auto-renew option (happens with either) (my other membership type settings included rolling period and 1 month duration)
2. Create a new membership price set
3. Add a radio button price field with the single membership type created above (this was the minimal condition to make it work. I discovered it when trying to add multiple membership types connected with the same organization- all recurring, but to recreate it you only need this one)
4. on Save the error pops up, not letting you save the price field.
