MP3 and Flac Encoders in 17.3?

Hi there, I am new to this forum and I need help with 17.3 in Windows 10 (64bit)-

I always used the CD Ripping function in Kodi but since I changed from 16.1 to 17.3 I am not able to use MP3 or Flac Encoders. There is only AAC and WMA Encoders in the options!Confused

Is this function deleted or have I to install it by myself?

Thanx for help and sorry for my bad english.Cool
