My first response would be a worn impeller. The hose seems to be hooked up to the bottom of the oil pan.
Plus, I feel I should fill the regular way. Pour the oil into the filler cap. To fill with the exchanger you would pour the oil into a bucket and push it into the engine. So, all the dirty oil in the hose is going back in. Plus, it's not that hard to just pour the oil in.

There's another valve on our X-Changer connection to the genset drain/fill hose... located at the generator. Until I found that and opened it, the symptom was exactly as you describe.
Our X-Changer drains/fills both mains, both gears, and the generator. I tend to drain mains and genset first, then gears... since the gear oil is always clean and it at least cleans the exterior X-Changer hose before refilling. The hose run from each engine's discharge outlet to the X-Changer is relatively small, so I'd think there's not much there to worry about, maybe less than whatever's left in the oil pan.
And... we don't have routine overhead clearance to refill the mains through the top anyway, so we use the X-Changer to refill... and haven't really noticed any issues from that. I'm thinking ( hoping) anything in the new oil, leftover from the old oil, will be quickly trapped by the new filters.
