"exclude from build" remain stored after file deleting

Hi all.

I’m using Code Composer 5.5.0.00077 and I’m observing a strange behaviour. 

I excluded from build a file (for example console.c) and the icon of the file changed as follows

After that, I deleted the file from the system because I didn’t need it any more.

Time later I inserted again the file in the project because of trials and the result was that the file appeared “excluded from build”. I spent some time to realize this because that file was no more present, so the new insertion should not “remember” the old settings.

It seems that the name of that file and the last settings about it remained stored somewhere in the system also after the file deleting.

Is this a bug?
