Error Male NPC don't attack Melee

[Brucasco]

Hello, i am having a strange problem with my Skyrim game:

For some reason, all male NPCs don't attack me in melee (with swords, axes or other close combat weapons). They just take out their weapons and walk around me talking menacingly, but never attack......

Males do attack me with bows, crossbows or magic (distance combat weapons) and females attack me both ways as usual. But males don't attack me melee.

Searching a bit, i found that apparently this might be an issue caused by Nemesis. I found 3 posts about this on the Nemesis Github but apparently none of then got a propper fix 

https://github.com/ShikyoKira/Project-New-Reign---Nemesis-Main/issues?q=is%3Aissue+is%3Aopen+melee+attack

Does anyone know how to fix this?

PD: All of my mods have been sorted with LOOT and cleaned with TES5Edit, so there should be no problem there......

Hello, I play in skyrm LE, I use mo2 and FNIS: what usually happens to me is the same, I have put several weapon packs in the leveled list and sometimes I get npc that chase me or run everywhere with a weapon and apparently they don't know that they have it in their hands, I tried to disarm them with the shout and force them to pick up the weapon or equip another one from the inventory and it worked, moral of a fable:
-See if you have mods that modify the AI in combat and test if those are the conflict
-In FNIS you must check specific genders for male and female, I assume that nemesis is the same and you have probably already tried it but try to remove any mod that could generate some conflict and try again
-Any mod that needs a requirement?
-I don't know anything about that PC exclusive mod, do you know which one I mean? Could it be something misconfigured somewhere that Skyrim is trying to use something it shouldn't and that's why the NPCs don't know what to do?
-I'm blindly throwing out ideas, you don't clarify if you use vortes, mo2 or if you install them manually, if you are in SE AE or LE, although this is the community for LE, I have sometimes seen messages appear that are not from LE, you don't clarify if Your pj is male or female. I don't know, I hope that some idea that you haven't tried works for you or helps you find some other route to get to the problem.
-use ReSaver to verify that there are no loose scripts that should not be
-I can't give you another idea since I play with female pj and the Feminized Level Lists mod so male npc are only some that have remained, the rest of the npc are female

good luck and wait for someone with experience can see your question
