r.average stores the category/average mapping in the history, which is
limited to 50 lines.

If you need to know the correspondence between the category and the
average, either use e.g. "r.stats input=category_map,average_map"
after running r.average, or use "r.statistics method=average" in place
ofr.average. r.statistics will create a reclass map with the average
stored in the category label.
