Logic Pro x converting stereo interleaved file into separate mono left and separate mono Right

Here is the link to the youtube guy that talks about this prolem

Thank you for your reply. It did work with bouncing first left then right, I guess mute option is set by default, something I overlooked. thanks again.

Thanks for getting back to me. Your procedure worked with left channel creating new mono left. It also greyed waveform on original file being bounced, not sure what that means

After changing to right Chanel and bounce in place it created new track with right mono Chanel but it also flattened the left mono channel created first. So it only worked for first in my case left channel.

If you watch the video, that's what I am trying to do. When I convert to new files as interleaved to split, it actually creates 2 additional files half the size of the stereo, but I can't import either one of those as mono, they shoe on timeline as stereo waveform, it kind of like logic imports the original stereo file instead of monos L or R.

BTW when I right click file, scroll down to Convert and then choose create new file (s) it actually is creating 2 different files, when I import into audition it shows mono files. But when I drag either one of those newly created mono files into the Logic's timeline or into new audio track it somehow imports stereo file or both of these files. Guy in the video actually manages to rename them and then he is able to bring them in as mono. In my case renaming wouldn't work. It only workedafter I closed logic and renamed these files, then I was able to drag them in as mono files, except when opening Logic again it had asked for original files that since have been renamed.

I hope this makes sense. and thanks for your time.
