3 RSI in same windows not working properly. Please fix this bug!

• 3 RSI in same windows not working properly. Sometimes 1 or 2 RSI are updating. It should be 3 RSI. 
• I want to display the labels as whole number not double/floating number. 
• Why this indicator is so slow upon loading?

Please fix this bug!
