We're running WP woocommerce website, we got there problem with generating links.

Steam api is generating link in this format: steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20S76561198030116216A15860401386D2594883032411162261
but wordpress is changing link into this: https://rungame/730/76561202255233023/+csgo_econ_action_preview%20S76561198030116216A15860401386D16457881814965865661
Its removing "Steam" and replacing with HTTPS. Does anyone know where is problem? We're using Cloudflare and I tried disable feature "Automatic HTTPS Rewrites".

Thank you a lot for helpful replies. :)
