Why bilal R.A name was not included in the names of ten sahabas to enter paradise?

I have seen a hadith in Sunni references that > Abdul Rahman bin `Awf said: The prophet (PBOH) said: > > > - Abu Bakr in Paradise > > > > - Omar in Paradise > > > - Uthman in Paradise > > > - Ali in Paradise > > > - Talha in Paradise > > > - al- Zubair (bin al-'Awwam) in Paradise > > > - AbdulRahman bin `Awf in Paradise > > > - Saad (bin Abi Waqqass) in Paradise > > > > - Saeed (bin Zaid) in Paradise > > > - abu 'Ubaida bin al- Jarrah in Paradise > > > —Tirmidhi There is in a hadith that the Prophet(PBOH) said that He heard the sound of footprints of Bilal R.A. So, in the lifetime of Prophet(PBOH),He said that Bilal R.A will enter paradise. Why his name is not included in this hadith.
