QGIS Plugin: visualization does not work in a particular date

I´m trying to see an index derived from a configuration utility in QGIS using the SH Plugin. The visualization works well except for an specific date (2021-02-05) when only one of the polygons shows the index. Any other date would work as it can be seen in the left image where the 5 polygons show the index. I tried to move the minimum and maximum values to be shown but it did not work. What can be the issue here? Thanks.

Can you install Network logger plug-in and provide the request URLs that are triggered? (do mask second half of insance ID to prevent from abuse).

My first guess would be that you are looking at the area where two Sentinel-2 scenes are stitched together and either the upper one is missing or it has a cloud coverage higher than what your configuration allows for.
