If there is nothing to do about the tenon because they would be stuck in the summer, then for a wobbly tenon possibly the cork is too thin, too thick or both. By too thin, it just means too thin, so it isn't gripping enough and even less after a short while. Too thick means a very thick cork was used so it compresses relatively fast, and both means that even this thick cork is not thick enough. Using even thicker cork is not a good idea.
When a tenon cork needs to be very thick, one method that I was taught and found it is excellent, is to first glue a layer of rubber-cork (aka tech-cork, gumi-cork), then glue the real tenon cork over that. The rubber-cork is harder and doesn't compress so much like the cork, so not great alone, but for a first layer it is excellent.
