The SRD states that a Lycanthrope has an LA of either +2 or +3, depending on whether it is afflicted or natural. Aside from that, its ECL is affected by several Racial Hit Dice, depending on what animal it is.
I am currently trying to make either a natural Wereboar or Werebear of ECL 8. This SHOULD be possible, since the wereboar has 3 racial hit dice, LA+3, so ECL 6, which room for 2 class lvls. However, when I fill this in on Heroforge Anew, it says my ECL is 11. Is this a mistake of the program, or am I missing something?
