Behind Enemy Lines: Glitch when switching companies

Well, the new achievement 'Behind Enemy Lines' gives the ADS mount for winning 200 Frontlines battles between any of the 3 Grand Companies. This means that the counter should continue to increase even after switching companies. Well, today I did use my free switch to go from Maelstrom to Twin Adder. I was sitting at 13 wins from Maelstrom. Today, I went into Frontlines, the new slaughterfest, and won most of the matches I was in. It shows in the achievement "A Line in the Glade". However, in the behind enemy lines achievement, the counter is not increasing with the number of wins. Probably because it was tracking for Maelstrom, and I'm no longer a part of them. If it is really 200 wins between any of the 3 companies, it should still count every win. This bug needs to be fixed since I want to work towards the ADS mount, but can't if it's not going to count my wins unless I switch back :(

I believe the "combined" reffers to slaughter and secure.
