Hg2 and vtc6

Git a smok gx350. Was using hg2 3000mah batts. Decided to upgrade to vtc6 3000mah. After using the vtc batts for 2 months i notuced the hg2 batts didnt fit my mod as well as before. It looks like the vtc6 batts are slightly taller and have warped the batt cover. Theres a small gap where i can see my batteries between frame and battery cover. Has anyone else experienced this. Is there a way of fixing the misshaped battery cover. Thanks.
