OpenWRT on H68K Unable to upload a OPVPN Client config the button is missing

Hi there I recently flashed OpenWRT R22.11.13, when I look for the option in the OPVPN client config upload the button is non existent. Is there some work around to add this button or will I need to flash a different firmware like 22.03.2? If I were to change to the different firmware which one would I need exactly?
