having trouble with the "read"

 I know this will probably end up my fault. I put my RK Mountain on the three rail layout. It is fed by my TIU #4. All other TIU's are off. I tried to find the engine in my engine list and it's missing. I press read and I keep getting weird results?

The first time it found a lash-up in address like 99? Whatever address it was I deleted it. I then tried to add the engine. It says no engine to add?

So I press read again, This time it finds a lashup in address #88? Nothing else is on the rails BTW.

So this time I move the lash-up to address #89. I press read again and it finds that same lash-up in address #89?

 Maybe this engine got lost or got deleted before? I will use the loader to see what address is on the board. Something seems wrong.

This is not the first time since upgrading to 6.0 first and now 6.1, that the read has not worked for me. Again it could be that I did something wrong with my housekeeping. I feel as though the DCS version is having trouble with TIU associations though.

I only report this in the interest of finding any issues that maybe out there. I know I can fix it at my end. It is like the fourth time this issue has bit me so I'm thinking maybe it's not just me?

Edit: maybe I found the first problem Somehow there's 2 TIUs with both at address #2.

So I moved the 3 rail TIU to address #4. Not sure now how to proceed. I need to re-add TIU #2?

I pressed read again and still no engine. The fact that it is missing from the remote should be my clue of something. I would not have deleted it on purpose.
