Y'all,
This is entirely normal due to the peculiar locking mechanism of the Lee action.
Since the action cocks upon the forward travel of the bolt (not upon lifting of the bolt, like some Mauser actions do) all the remaining motions of the bolt are "dead". Hence, there is nothing really strong to retain the bolt in its locked position. A few degrees lift upon firing is not only normal, but was appreciated in war-time (and still is by competitive shooters) because it makes follow-up shots faster.
Hope it helps.
