Oliver 550 strange acting hydraulic

David Bégin Hi guys, i have an Oliver 550 with a front end loader plugged on the main hydraulic system.

I got a problem when lifting thing with my 3 point hitch. So when i am lifting with the 3ph, the single acting cylinder on my loader lifting arm wont lower anymore. It only go up instead even when i'm pushing to lower it. When the 3ph is down to the ground the single acting cylinder function normally. Like if lifting the 3ph would create a positive pressure in the free flowing system. Could it be something wrong in the 3ph valve or should i see this as something normal?

Thanks for your help!
