combinational loops as latches

all the latch instances for "equivalent circuit" warning comes from

always @(posedge clk or posedge reset) begin

if(reset) begin: OVER_LOOP

... ;

end else if (clk) begin

... ;

end // end of if OVER_LOOP

end // end of always

When I double click all 42 expanded warnings, it goes to the same statement "end else if (clk) begin".

However, for the warning "TimeQuest Timing Analyzer is analyzing 24 combinational loops as latches", when I double click it, there is no highlighted line in the text field (.v file).
