    It would appear your third variable is the glue, even if silver
    compatible, it maybe in conjunction with the leather other by
    products are created. also, you didn't mention what tonnage the
    leather is, the two basic are either organic vegetable (oak) or
    smoked, the second being chrome tanned (or other metallic salts). 
    actually every tannery has several unique formulas for their
    leathers, so leather from two companies maybe called the same but
    with different additives that could be reactive catalysts. 

    Your best bet would try a different leather source, then retry your
    test with a variety of adhesives. 

    Warning: "Craft Store" leathers may have the same packaging, but
    multiple tanners, plus each color is a different "brew" of
    chemicals. 

    Sorry I'm unavoidably vague, but I've been out of leather craft
    quite a while! 

Have fun, Ed
