Thank you. I realized I did have a pano made after all, but somehow ended in a different folder. I feel LR screwed up at some extent with my catalog, it kept missing some photos and they (and many others) showed up after I checked the "treat jpeg as separate". Problem was none of those hidden or neglected during synchronization was actually a jpeg associated with a raw file.
I'm attaching the initial pano; again, my second take was made in PTGui and was able to use more of the frame.
