several red dots / pixel in ray cloud?

Not sure if that was already before but after updating to latest release of Pix4D Mapper and re-processing a mission (after adding manual tie points) i’ve several red dots / pixel in the ray cloud. They are spreaded all over the map.
Do they have some special meaning? (e.g. not enough image information at this pixel)

If a pixel is not found, then is not created, red big dots are cameras that have not been calibrated.
If you place a screenshot somewhere and share the link, then I can see in more detail…

I’d like to open up this tread.

We got the red pixel problem in out point cloud. This is not az uncalibrated camera. These are points in the point cloud.

Please see attached screenshot.
