Partial reflectance map and wrong band order

I’m a newbie with Pix4D and I’m having issues with my first results. Espacially with my reflectance results (see below)

This should represent a raster stack of my 5 bands (true color). You can see that only few strips are showing and it seems that my bands are in the wrong order because it’s supposed to be true color’ 3-2-1 or Red - Green - Blue in QGIS order ? (I’m using QGIS virtual raster to display it)

Any ideas?
Best regards,
