About ranger armor

Hello everyone. I hope somebody here can help me.

In the guild wiki, it says that insignias can't be applied to collector armor, you know, that one you can acquire by exchanging common drops in a zone. However, I just had, with my ranger, a Krytan armor, 61 AL, obtained in the Maguuma Jungle from collectors, and I DID applied to it some insignias; radiant and survivor insignia's, to several parts of the armor.

Now what's going on here? Since I only own Prophecies, I don't have many options, and personally the not-elite armor doesn't looks what I would like; however, I do like the Krytan, but I would like to know if that of the insignias that can't be applied just cover the maxed armor (haven't gotten to Crystal Desert yet), or perhaps just the profession specific insignias.

Thanks in advance for the help

Only collector max armor can't have insignias. I believe all the other collector armor can.
