1. Is it related to this? [No marker for slider online](https://discourse.psychopy.org/t/no-marker-for-slider-online/7679)

2. That seems to be something with the OpenIAT task in particular. You aren’t the only one seeing that: [Problem with presenting stimuli in OpenIAT](https://discourse.psychopy.org/t/problem-with-presenting-stimuli-in-openiat/11741). I think it’s the “Text\_stim” component on the trial. If you aren’t using it, remove it? Or add a column for it in whatever is controlling the trial loop and make each entry `' '`, which should render as blank.
