I have a hunch, when you made the sheet, did you by chance change the setting, then click away, then change it to whisper? because, if not, it could be a simple "Null Ref" bug, in which it searches for the variable to tell it "is whisper?" and finds nothing, so it simply changes nothing, this, not adding the "/w gm" (which is specifically what it adds btw, not joking, you can find it in the community 5th edition sheet on the 3rd tap, switch it to a NPC, that's 1 variable, then change the NPC stuff to everyone, then click away, then change it to GM only, the clicking away is important , then chect the Attributes & Abilities section, sure enough "/w gm" is the variable) This also leaves a very OBVIOUS vulnerability in your secretive rolls, you need to add "/w gm" to every line! for example: this entire line will get whispered to the GM no matter how long I make it, no matter how much I type, I could even end up finding some kind of upper limit on the Parser and crash something, but this entire line will still be but a single super long Whisper to the GM
this is in Public view, it didn't start with /w gm
/w gm this line however is hidden! do you see what I mean? the "Whisper everything to the GM" setting works, until you submit a new line (Carriage Return, New Line, or Both, doesn't matter if it's via Enter Button or Not, although, I do notice that this Site is apparently built without Carriage Returns! meaning this is either a Unix/iOS format, not Windows) for any future problems, first ensure this protocol is tested FIRST
