Texture2DArray asset thumbnails are not reflected when the source file texture is changed. Once a Texture2DArray asset is opened and loaded, the thumbnail will follow any subsequent source file updates.
Update "T_sources_B" asset thumbnail.
Update "T_sources_B" and "TA_sources" asset thumbnail.
("TA_sources" is Texture 2D Array asset which is referenced to "T_sources_B" asset)
