At first I removed these tiles from the shelf and the glue that was on them smelled horrible, and after cleaning and scrubbing the shelf I decided to have it torn out and a new one put in. However under that shelf I found the same tiles on the sub floor, however this glue was on the sub floor and it was not covered with tiles. Who knows they probably glued the entire area and ran out of tiles. I sprinkled the floor last night with baking soda and it did absorbe some of the smell. My repairs man is here and I suggested him putting a piece of new subfloor on the untiled area. I am having a new subfloor installed in my upper bathroom so I am hoping to have a small piece left over enough to cover this area on the other bathroom. If that does not solve the problem then I have no idea how to fix it, only to take the subfloor out and that will be impossible. I felt all along it was more of a toxic smell than a sewer type smell. I will find out later if the new piece of subfloor will take care of the smell.
