Accordion Block Dividers Glitch "Show First and Last"

Hello! In the Accordion settings I toggled off the "Show first and last" and kept the "Dividers" toggled on. Anytime I try and duplicate this section, it shows that the first and last are toggled back on which ruins the design. Is this a glitch? How can I fix this? Is there a custom css to hide the first and last dividers only? Thank you. first and last dividers toggled on automatically after duplication 

this is how it should look without first and last dividers: 

Hey this worked! Thank you.
