It is not a bug -- this is the way the pattern-matcher works.  You need
to use ReplaceRepeated, i.e.,


	"expr //. rules repeatedly performs replacements until expr no longer

instead of ReplaceAll:


	"expr /. rules applies a rule or list of rules in an attempt to
	 each subpart of an expression expr."


	k1matrix=Table[k1[i,j], {i,4},{j,4}] //. {h->6, e*in ->10^6}
