item data defects w.r.t. modifiers

Item 1267518888 has an unusual defect where it shows two different intelligence modifiers, one for +18 and one for +40.   Another item has two health modifiers, item 792204700, but both are identical.  There are several (perhaps 6) items which have duplicate statistics, either with the same or different values.  In game, this is displayed as two modifiers.

I don't know how to handle this sort of item.  I could display both values of course, but I suspect these items are actually broken in terms of what is expected.  It certainly thew my display code for a loop when I found an array of hashes where I expected a single hash.

Another item, 1554665099, has two "cold" modifiers, but both are of different types:

 "cold" => [

    {"type"=>"hpdamage", "displayname"=>"cold", "value"=>1},

    {"type"=>"mpdamage", "displayname"=>"cold", "value"=>1}

]

My decision here was to just not display anything about the second item.  This item is unique so far, in that it is the only one with a single "key" of "cold" but two different "type" values under the array.  It also displays in-game with the green bug display, so perhaps I'll not worry much about the decision I've made

But, I handle this one now too:
