An earlier post said the point-group is P2, and these reported cells do not quote the beta angles: what are these angles?. In the monoclinic system it is possible to have two closely-similar alternative cells in certain special cases, and if the crystals have been indexed differently this could prevent their merging. The program Pointless would sort that out for you.
