[NT6 bug?] Compiles the wrong indicator

[FireFly]

First I compile indicator 1 ("CollectVolumeProfileData"). The compilation fails.
Then I create another indicator ("2CollectVolumeProfileData") and try to compile.
However, NT6 then still start to compile the first file. I have to fysically remove it to make NT6 compile my 2nd indicator.

Bug or am I overlooking something?

As you press compile NT compiles all indicators and strategies into the same DLL/assembly and you will get reported any poetntial error in any of those files.
