Maybe you need a taller, less shallow kind of mixing bowl. A short squat bowl needs more volume in order for the SB to submerge, but a tall thinner bowl needs less volume for a SB to submerge. I would look into finding a taller thinner mixing bowl in order to make smaller batches of soap.
I, too have had fragrance oils or essential oils re-absorb after a few days, but also once or twice the expected re-absorption did not happen. Only time will tell if it will re-absorb. The two times I didn't get re-absorption I had to make the decision of what to do with the soap. The first time, I tossed it as a total failure. The second time, I attempted to re-batch, which worked out, but by then I had more experience and a better idea of what had gone wrong.
Also, as a point of interest, I did this with a huge batch once too, and with a very strong fragrance that I had never used before. I have learned not to make large batches with a new-to-me fragrance. It leaked horribly. I hated the fragrance, too. Well, I cut all the soap and it just kept on leaking. So I stacked them all in a large plastic mixing bowl on top of each other and set it to 're-absorb' (or whatever it might do) in the upstairs bathroom because I couldn't tolerate the smell in the main part of the house. It took a long time to re-absorb. I think I left it there for at least 2 or 3 months. Some probably evaporated, as well, of course. Anyway, I still couldn't stand the smell. It was so strong and spicy sweet, just not to my liking. That's the batch I rebatched. There was so much of it, that it seemed like I was re-batching it forever, but I really learned my lesson about making large batches of soap with an ingredient (this particular fragrance) that I had no clue if I would like. Not only did I re-batch, I also used some of it for confettti soap, AND I also salted out some of it. It was just too large a batch.
