NPC Spawn Issue: a giant beetle in West Karana

[BleuStones]

I have been running all over West Karana looking for these giant beetles to collect their giant eyes, however, I have only seen the regular "a fire beetle" roaming the zones. In addition, I have found a single static spawn of "a giant beetle" in the same zone. This beetle doesn't path when spawns. I just wanted to see if this is normal or should there be more "a giant beetle" roaming the zone. Furthermore, I don't believe the "a giant beetle" should be dropping regular fire beetle eyes. Thanks for you time I appreciate it thank you.

On the other hand, I haven't check in Toxxulia Forest for the same issue, I'll update on this as soon as I do a check.
