Hi,
I discovered a bug whilst the fueling operation was under way. I finished fueling, so the fueler walked up to ask if I was finished or needed more, but before I could select any of the options in the fueler window, Jenny called over the cell phone, so I answered. It was regarding the passengers if they could board, I replied "YES". After the FBO window disappeared the fueling info window never came back. It was also not possible to call the fueler via Jenny, as this option was greyed out (thinking it was still active). Which is actually correct as I never replied the fueler and also the fuel truck was still there. I eventually taxied out and the truck disappeared.
I also mentioned to @Graeme_77 on Discord
