Incorrect drive labels outside of DOpus

Just started using DOpus, and it's great aside from this small problem I'm having.

I have a few flash drives, each with different names. If I open My Computer (I have DOpus set to replace the default explorer), whenever I plug in one of my flashdrives, it shows up with the correct name. However, if I go into a program such as notepad, photoshop, etc, anything with a Save As... or Open.. window that comes up, it shows the wrong drive label.

For example, say I had flash drive 1 (FD1) plugged in before I had installed DOpus, whenever I try to open a file from that drive in a different program, in the window it still shows up as FD1. When I actually go into it, it shows all the files from the actual drive, but it just displays the drive as FD1 instead of, say, FD2.

Is there any way to fix this or change some settings to fix this problem?

I'm not sure I've understood the issue. Could you post a screenshot showing the contradiction?
