After Masterworking/Enchanting an item - item comparison stats are broken

I have a 2h mace equipped MACE1(4/12MW 297 str 1936 life), and when comparing it to MACE2(4/12MW 191 str 1592 life) - the second mace reads correctly (red text -106 str) - but incorrectly (green text +624 life). Problem persists after logging, zoning, placing the second mace in storage. When swapped with MACE2 equipped comparing it to MACE1 the values are correct (green text +106 str) and (green text +344 life).
