Quickly checking the wiki suggests there is a threshold of 20 kills to hit before being featured for those bosses you've listed:
"To be featured in the Boss Killcount HiScores, you will currently need to kill a boss or complete an activity at least 20 times. This is true for all bosses and Boss Killcount activities, except for Bryophyta, Chambers of Xeric: Challenge Mode, Hespori, Obor, Skotizo, The Corrupted Gauntlet and TzTok-Jad, which all require just 5 'kills' to be featured, and The Mimic and TzKal-Zuk, which just require 1 kill to be featured. "
So in other words, crack away at them a little longer and you'll make an appearance. I too look forward to doing bossing. I've played the game since what feels like the dawn of time, yet have barely touched that type of content...
Playing Runescape since 2006. Friendly guy. Technical in nature. Currently working on what will no doubt be the most powerful old school account ever to walk Gielinor.
