I have brought this issue to the attention of SDL a number of times, to no avail. It has to do with the "log file" (Go to the File menu and choose View Log File; go ahead, try it). I can't help but think this is a non-issue, but if that is the case, why it keeps being included in the Log File. In this particular case (still happening in the newest Studio 2019 Version 15.1.3.55768) the issue at hand, in the file I analyzed, is registered as a warning 167 times (56% of total entries related apparently to the same issue) in a log document with 293 entries (!) of which 278, in general, are warnings. It seems to me that Studio, in this particular instance, is running legacy code that generates some "warnings" which are completely irrelevant.
