It should be like [this] (https://d1u5p3l4wpay3k.cloudfront.ne...fff7b4f00801d3) but instead it look like the normal icon of [null field] (https://d1u5p3l4wpay3k.cloudfront.ne...8bad3bfccb743a)

Is this intentional? Any chance it's going to be fixed? Other set that has customized icon also have a problem like this

thank you in advance
