Everything is good with mercury but why are mercury qualities not visible??

Person cannot pronounce clearly specially the alphabet’R’ instead speaks ‘L’, lacks general mercury qualities like socialising, communicating smartly, attention to detail, and more, but has Jupiter in lagna so intellect and wisdom is there, mercury in 11th house with sun in rashi of virgo, mercury is retrograde, and in hasta nakshatra, name is vikash (simple).
