Door Closing/Opening Glitch

I was on a server and we had towers to live in for the night in my faction.I went to open my door, it opened fine.Then when i went to close it, I thought it would just close, but it closed and then re-opened.It did this about 15 times.If you are on the block that the door is on, it works fine...sometimes.If you're on a block that is one or more blocks away from the door, you can close it, but it automatically closes again.It would be nice if you could figure this glitch out.Thanks!
