Required Gas changes when try to change Gas amount when sending token.

Hello. I have seen this bug when trying to send 10000 tomo coins to another address. I can show it to you via video so you can easily figure it out. As you can see on the video, the required gas changes when i tried to change the gas amount on sgas settings. It may create some conflict as it will not show exact required gas for every transaction, and which changes when yoi try to manipulate the gas settings.
