Re my question of Dec 16, 2015 "
Six months later and the same problem is back. I always use an ICC profile in the Print Module's Print Job/Color Management window. When if I leave the print module to do anything at all (eg, Library Module, Develop Module, shut down and restart...), and then return to the print module, the Profile setting is empty and I cannot print until I manually select a profile again - usually the same one. I shouldn't have to do this. It's supposed to "stick."
This is impacting my productivity with Lightroom.
In December, I created a new Catalog and that fixed the problem, so I imported from the old catalog and went about my business. All was well until a couple of weeks ago.
This time, a brand new Catalog continues to exhibit the same problem, so I don't think re-building my existing catalog would help.
I am on the latest Lightroom CC running Windows 10 x64 with the latest Epson 3880 driver (6.63). The same problem appears on a Canon MX920.

I discovered a workaround.
Delete the print presets that don't work properly, then re-create them from scratch. The problem of the chosen ICC profile disappearing for those profiles goes away and they work as they should.
Still, it would be nice if you could fix this.
