This is a bug where SaT is thinking the rebuy window is an actual poker table.
Can you take a screenshot of the window?
Also, in SaT, there is a built in hidden hotkey: CTRL + ALT + SHIFT + T
It will copy the titlebar text of the window and some other info to the clipboard.
Please mouse over the rebuy window and press that hotkey, and then paste the result here.
And then do the same for the actual table that it is related to.
