How to turn off indoor temp display on main graph?

Initially I thought you had the answer for me. I restarted and no indoor temp display, but then came back into the room a few hours later and it was back.

I now just downloaded10.37S72 and installed it.

Restarted, Indoor temp gone. Three minutes later it was back.

What is weird is that the other instance of WD (also updated) is running on the same computer, being fed by a similar station (a Vaisala WXT510 instead of a 520) and it never has and did not start to display the indoor temp. Weird.

Any thoughts or should I just let it be?

Thanks, Dale
