In developer portal, if I am defining any field with a json in the options attribute, the the value is getting reflected in the content-type field inside resource summary

[#1]

To define a field variable as drop down list, I define it with a json. e.g.

Field name : Accept

Options: [ "application/json", "application/xml" ]

It is working fine, but the then in the resource summary section, the Content-Type field section present the same value. it is not only for this Accept field, even if I am defining any other field with a json, it is coming in the Content-Type field. here in the below picture, you can very well see, the content-type field contain data of two fields, one is Accept field and the two numeric values are from another field.
