Cannot set custom quality level for AAC/MP4

Hi all,

I have been using LameXP for over a year - excellent program! However, I'm running into a bug when trying to encode using AAC (qaac 2.66). I don't encounter this problem with either OPUS, MP3 or Vorbis.

I'm currently using Version 4.16, Build 2134.

The problem is this: under the advanced settings tab, when inputting a custom encoding parameter for AAC (in this case, simply: "--tvbr 87") the encode fails, every time.

When inspecting the log, I figured out what the problem was:



As you can see, instead of replacing and overriding the default quality setting (--tvbr 91, which the slider is set to under the Compression tab), the custom setting that I want (--tvbr 87) is just appended to the command string, thus conflicting with the first setting. Naturally this means that the encode stops in its tracks before it can do anything. It throws up this message at the bottom:



Please let me know if you can replicate this. It's the only thing holding me back from using LameXP for AAC encoding (which is otherwise first class).
