Funny that the symbols would tell you to not fill the filter until after the previous symbols tell you how to install and tighten it.
Certainly, it's not a requirement to fill the filter. But they aren't saying that it hurts anything either, except the silly assumption that new oil is unfiltered and dirty.
I wouldn't be surprised if they just don't want us simple folk to spill oil on ourselves, slip and fall, and then sue them.
Maybe they even assume that some folk will want to add oil from an open 5 gallon bucket out on the farm somewhere, who knows?

Well then, I guess I just lost all respect for Baldwin tech support, because that is pure horse manure. I'd be much more worried about initial flow and media collapse than having clean oil in the filter. The lube system flows many gallons per minute while running. The alleged issue of a quart-and-a-half of "unfiltered" oil present at startup as rationale for not pre-filling a filter is just ludicrous.

I'm sure it's been covered but the owners manual says to pre-fill the filter. or am I seeing things

Next why would you be so worried about the un filtered oil in the filter? I know with the foil on top of some of the oil jugs and some people not being careful and letting this foil get into the filter and clogging the oil galley.

These other reasons not to pre-fill are hogwash.

Where do you pour the oil into your engine? This "unfiltered oil has already been all over your valve-train.

This "unfiltered" oil is clean unless "you" contaminated it.

Pre-fill your filter.

4. Add 1 turn
5. Check for leaks
6. Dispose of properly

If #5 was a "do not pre-fill" message, it would be step #2. That reply from the Baldwin guy is probably a generic reply to the question of "do I HAVE to prefill the filter".
I don't see how prefilling can possibly harm a filter. For me to believe it, I need a good reason. My .02
DING DING DING. We have a winner. Symbol #5 on the Baldwin filters does mean "Check for leaks." Per Travis at Baldwin tech support. He said as long as you do not use a pressurized nozzle to fill the filter, there is no harm in pre-filling. If your re-using oil, which must be a common practice for OTR drivers, you should pre-fill through the little inlet holes as opposed to the threaded outlet hole. This keeps contaminants on the "dirty" side of the filter. If using new oil, it doesn't matter.

I agree 100%! Yes, you get an A+, so give yourself a pat on the back, then have some cookies and milk.
