I've read several posts on this forum where people have reinstalled their front calipers on the wrong sides (passenger caliper on driver's side and vice versa). It's a common mistake that makes bleeding impossible.
How can you tell if they're on the wrong side? Just crawled under... bleed valve is facing the back, at the top of the caliper, an inch or so higher than the brake line. Wouldn't it be upside down if switch L vs. R?
Valve clearly at the top. That spray is left over from the 1st of 3 bleeds.
