Question about Signal Levels

I had a look at my signal levels and see the following:

Is it normal to have the Channel ID not equal the Port ID?  I am seeing channel 1/17 and port ID numbers flipped.

Re: Question about Signal Levels

@mahomed It is normal that the channel ID and channel number don't match, nothing to worry about.

This is my signal levels for example, notice my upload levels:
