Sankey error - image when full white

[OkFranco]

Hello,

On March 9th I refreshed my dashboards and my Sankey visualization when full white. I cannot see it despite I know it is there. I can select it in edit mode and change source as well as change backgroud colors. Despite that I cannot see the flow of information. In addition on March 8th everything was ok, so it is potentially a bug generated between 8 and 9 of March.

Let me know if you found such bug and if you were able to correct it.

Best,
João
