V5 channel subscribers bug

[Proddy3]

Because the Helix API doesn’t support providing a channel id and returning all subscribers, I’ve tested on the v5 API and encountered a weird error.
I tested on a friend’s channel and it returned this regarding one user:

{
	"created_at":"2019-07-10T20:31:34Z",
	"_id":"d851c906561bbc77e2c3dffd3d363e3b7f2f6be7",
	"sub_plan":"1000",
	"sub_plan_name":"Winter's meme team",
	"is_gift":false,
	"user":{
		"display_name":"MxLuminescence",
		"type":"user",
		"bio":"I play games and do art. Pop in for some fun convo",
		"created_at":"2012-12-01T01:22:10Z",
		"updated_at":"2019-04-13T16:39:01Z",
		"name":"mxluminescence",
		"_id":"38105363",
		"logo":"https://static-cdn.jtvnw.net/jtv_user_pictures/87854437-dc8b-48bc-91e1-fec5936e5060-profile_image-300x300.png"
	},
	"sender":null
}

However when running just that one user through the Helix API:

{
    "data":[
        {
            "broadcaster_id":"45215812",
            "broadcaster_name":"PopTartPony3",
            "is_gift":true,
            "plan_name":"Winter's meme team",
            "tier":"1000",
            "user_id":"38105363",
            "user_name":"MxLuminescence"
        }
    ]
}

The difference being, the Helix API correctly reports that it is in fact gifted. Is this a known or intended issue due to backend changes and the v5 being deprecated, or can this be resolved?

Thanks,
