EE 3.5 Channel Form - returns Invalid Selections on radio, multiselect, and relationship fields

I’m trying to create a form on Frontend so they can create an entry in a channel. I have a bunch of different fieldtypes being used, such as radio buttons, multiselect, single relationship and multiple relationship, etc.

I tried few diff options from the docs but not sure why it’s not working. When I use the field:my_field it at least spits out the markup with radio buttons and relationship boxes… however when i submit it says “invalid selection” for a simple radio button.

The javascript doesn’t seem to work for relationships either because when i select something on the left side it doesn’t get pushed to the right side like it normally would when inside the CMS creating that channel entry.

{exp:channel:form channel="my_channel"} <link rel=”stylesheet” href=”{path='css/_ee_channel_form_css'}” >

{field:my_radio_field}

{field:my_relationship_field}
