Waveforms view only show mean waveforms

Hi all,
I have an issue using the waveforms view. I can only display the mean waveform view and the button "toggle mean waveforms" does not have any effect.

Here is my phy folder : https://instituteicm-my.sharepoint.com/:f:/g/personal/anthony_pinto_icm-institute_org/EjKkyzBR4O5OvbYDfxM1R9sBHFJO2Mmn3hOWhgyv42xfYg?e=jwBj4v

Here is the log file if you want to have a quick look at it before downloading all the data.

I am a bit confused about the exact reason of this issue. I exported the data using the function from spikeinterface like that:

sexp.export_to_phy(
                waveform_extractor=waveforms,
                output_folder=os.path.join(output_folder, 'phy'),
                compute_pc_features=True,
                compute_amplitudes=True,
                copy_binary=True,
                peak_sign='neg',
                remove_if_exists=True,
                verbose=True,
            )

To add a bit more context, my folder is located at a very long path and it was the origin of a problem with the waveforms a few weeks ago as mentionned here https://github.com/cortex-lab/phy/issues/1219#issue-1880538192 but I found a workaround by doing that : https://www.howtogeek.com/266621/how-to-make-windows-10-accept-file-paths-over-260-characters/ so I avoided the windows limit of 260 characters. I though it solved my issue because with the previous issue the waveforms were not displaying at all and now I can see them.
I would like to find a workaround because I would like to avoid to move the location of the phy folder if possible.

Cheers,
Anthony

Start by reproducing the issue with the exported phy folder and the provided spikeinterface export_to_phy call. Inspect the WaveformView behavior around the “toggle mean waveforms” control and compare it with the logged waveform-loading steps. Done means the control visibly switches between mean and non-mean waveforms for a reproducible dataset.
