Question / Help OBS Minecraft Trouble

[HelpMePleaseLel]

I have 2 problems here. I don't think they require a log, but they might
1st problem:Everytime I pick window capture on sources, and I pick minecraft, it shows nothing, just obs.
2nd problem: I would like help with display capture on sources, I am wondering how I can make the size different, e.x:I don't want the recording to show my windows 10 menu bar or my tabs.
