Backhoe Kubota BX 23 S Backhoe coupler leaking

[Kubota Possum 2018]

Hello all! Back with a quick question. I walked into my garage last night and discovered that my backhoe for my Kubota BX 23 S which is currently sitting on a BXPanded backhoe dolly had a coupler which had leaked hydraulic fluid. It had the cap in place (blue one I believe), and had leaked a decent amount of fluid which ran down onto the base of my backhoe dolly. Someone please tell me is this normal. I am new to tractors (just purchased this back in July), and tend to worry when I see something like this. When I discovered it I cleaned the face of the coupler with a shop cloth, and recovered it with the cap. It hasn't leaked since to my knowledge. As a side note the bucket on the backhoe has leaked down and is now touching the garage floor. I was wondering if the backhoe extending itself may have pushed fluid out of the coupler. Like I said I am new to tractors, and was hoping someone could clear this up for me. Also, will I need to add hydraulic fluid to the tractor when I reinstall the backhoe later.

Possum,
Which side of the connector is leaking, male (plug) or female (socket)? Both should have a metal to metal ball or poppet type seat to prevent excessive leakage.

It is the end which plugs into the back of the tractor. I'm not sure of the exact terminology. They are flat faced couplers though.
