Custom header removed by cloudflare even though its been whitelisted

I’ve got a rails web app that when another electron app opens the site it’ll inject a header before the request. The header is always removed in a production environment though even though staging and local both work as intended. I’ve tried X-Appheader and X-APPHEADER. It looks as though Cloudflare is what is removing the headers from the requests. I’ve not set up anything with cloudflare so it looks like its an issue on renders side or a configuration i’m missing in my blueprint.

Does anyone have any advice
