Block JSON-LD markup of one property only

Hello,

How do I prevent WPSSO from creating schema JSON-LD markup for items of a specific property? JSON-LD markup is created for items “.wp-block-post-title” and   “.speakable” with the property “speakable” and each of these items generates an error message. I would like to have no markup with the property “speakable”.

            “speakable”: {

                “@context”: “https://schema.org”,

  “@type”: “SpeakableSpecification”,

                “cssSelector”: [

                 “.wp-block-post-title”,

                  “.speakable”
