Issue with routine containing Image component

I have built an experiment using builder. I am using images and excel files. Both of these are in the resources folder and both work in a number of the routines within the experiment. My problem is that, for some reason, one of my routines doesn’t work. The duration of my stimuli are drawn from the excel file and they work on the audio and text components. Similarly, the images are loaded and work fine on my ‘adaptation’ and ‘top-up’ routines. However, on my ‘test’ routine which uses the same …

I have rebuilt a sample experiment to try to find out what my issue may be. When I remove the condition file the experiment does run as expected. The condition file contains two parameters: Test_duration and Reference_duration.

When I add my condition file, the auditory component of the experiment works fine with the condition file (using the ‘Reference_duration’ parameter) but the image component does not for some reason. I am left with a grey screen once the experiment gets to the ‘test’ routine. For both of these I set the stop time in duration(s) and use their respective variable ($). I have tried using FrameN and duration(frames), changing the values accordingly in the excel file, but this does not help.

Is this a bug? Is there a fix to this issue that I am missing?

Any help is appreciated.
