NH 1411 cutterbar oil

I drained and changed the oil in the whole mower and I’ve ran it a couple times to make sure everything is fine with it. I check the oil today and 1 out of 8 modules had the correct amount of oil on it. Only a couple showed oil on the stick. I have a other 1411 that needs seals in between each module and the oil goes from one module to the next. This one I recently got is not doing that. It’s literally just disappearing. Not leaking anywhere from what I could see. Any suggestions here? I’m about done with new holland mowers. From several people I’ve talked to it seems the cutterbars constantly have problems with oil in some way
