Transparent Gray Notes
I was just arranging one of my favorite songs "I Need A Dollar" by Aloe Blacc and suddenly these gray transparent notes showed up. I'm thinking that it's a bug. But I suppose that I could have misclicked on something else by accident. Either way, it's something very very minor, I just figured I would point it out.

Click and press 'V' ?
It is better to use the forum https://musescore.org/en/forum/6
Oh okay, thanks! What is the intention of those gray notes anyways (out of curiosity)?
for special needs of 'appearance' or 'Playback' is one of several options for the score elements (see for example Inspector: https://musescore.org/en/handbook/inspector-and-object-properties#categ…)
MuseScore provides the ability to make notes invisible, but it's totally up to you what (if anything) you use this feature for. There are dozens of possible uses. You must have accidentally pressed "V" with that measure selected and thus inadvertently made in invisible.
