The difference is trek shields stop both energy and physical attacks while wars just stops energy,
Debatable. In revenge, anakin and obi wan had to take out the shields on grevious' ship before they could fly into the docking bay, it is quite obvious they have shields that prevent atmosphere from escaping for a docking bay, ray shields trapped anakin, obi wan and palpatine in the corridor (always really hated that part).
Plus, most ships fire energy weapons at capital ships by default. If shields could only protect vs energy and not physical projectiles, no one would ever shoot anything else at capital ships.
Basically, shielding is another area of SW lore that is not terribly well thought out and that the designers freely ignore when making a story (which is why it's fantasy, not sci fi).
