A 2015 Landsat 8 band 2 does not load into QGIS' Semi-automatic Classification Plugin window when wanting to clip multiple raster bands.
Bands are loaded from Table of Contents (TOC) as displayed above or clicking 'Refresh list'. The TOC (below) shows band 2 but, it does not appear in the SCP list. Years 2013 and 2014 do not give this problem.
