877	CCALF with multiple-slices	bheng		"The CCALF parameters are set just once at the end of the picture in DecLib::executeLoopFilters()

   m_cALF.getCcAlfFilterParam() = cs.slice->m_ccAlfFilterParam;

The pointer ""cs.slice"" just refers to the final slice in the picture at this point. For multiple slices with different CCALF settings, the CCALF parameters should be updated for each slice within the ALF loop using ""cu->slice"" parameters rather than ""cs.slice"" parameters.

I believe adding the line below would fix the issue.

      // reload ALF APS each time the slice changes during raster scan filtering
      if(ctuIdx == 0 | | lastSliceIdx != cu->slice->getSliceID() | | alfCtuFilterIndex==nullptr)
      {
        cs.slice = cu->slice;
        ''' m_ccAlfFilterParam = cu->slice->m_ccAlfFilterParam; '''        
        ...
      }
