The difference you see is based on what you have drawn and what the system sees as the main pipe size. By default, VPE P&ID sees the starting size of the line as the default size, and this is what it will show in the Engineering Explorer. If you want a different size to be the main size, then you need to set it manually.
The problem I see is that your 6" size label is actually sitting on an 8" section of pipe, so your graphical representation is incorrect. If you want the pipe labelled as 6", then you need to move the right hand reducer over.
If you want the pipe labelled correctly, then you need to delete the label that you have shown and place a new one off the upstream reducer (the 4x8).
And finally, if you want to set the main pipe size to be other than the starting point, you need to select the label that has the correct size you want, right click, and then choose "Set As Main". At my company, the largest diameter pipe is the main pipe size we want to see in the navigator (and eventually in the line list). So our drafters have to set the main size manually in some cases. They really have to pay attention to what they are drawing.
