Error with Fill Colour box in

Hey I’m new to PsychoPy Builder. I keep getting errors every time I try to type something in the Fill Colour box for a textbox stimulus? This is the error:

Traceback (most recent call last):
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\builder\dialogs_init_.py”, line 829, in launchColorPicker
colorSpace = self.paramCtrls[ctrlName + ‘Space’]
KeyError: ‘fillColorSpace’
