More issues with scribespells

[Zeice]

I have a quest turn in for lvl 66 spells, lvl 67 spells, etc.

Just those levels, here is the script.

sub EVENT_ITEM {

#level 66 spells - trakanon
if (plugin::check_handin(\%itemcount, 1267 => 1)) {
quest::scribespells(66,66);
$client->Message(7, "Zelus says, 'This is most interesting, and most ancient. Well I can show you how to read this and you will be on your way in no time!'");
}

#level 67 - gukb
if (plugin::check_handin(\%itemcount, 1270 => 1)) {
quest::scribespells(67,67);
$client->Message(7, "Zelus says, 'This is most interesting, and most ancient. Well I can show you how to read this and you will be on your way in no time!'");
}

#level 68 - mire
if (plugin::check_handin(\%itemcount, 1267 => 1)) {
quest::scribespells(68,68);
$client->Message(7, "Zelus says, 'This is most interesting, and most ancient. Well I can show you how to read this and you will be on your way in no time!'");
}

else {
 	    plugin::return_items(\%itemcount);
	}
}

Players are reporting that when they do the turn in for the lvl 66 spells, it's deleting many older spells. In the case of a cleric it's scribing their 66 spells but deleting Complete Healing..which is a big hurt lol. I don't have anything set up for traindiscs yet so I'm not sure if it's having the same issues still. Anyway would anybody be able to look into this please?
