Need Some Help Fixing STR Bug

So Recently i got a 2/10 Caster Amu for my Paladin and with that i decided i'll reset his Stats (after equipping 2x BK) and Stat him again.. And so i did and after stating him my gear was fully equipped and working a played a few days and after a while my gear would stop working randomly (armor not equipped when joining games etc...) so now i have to run with a 10FCR/+STR Ring is there anyway i could fix this?

I've tried Resetting his stats still refuses to leave the armor equipped as it was before having to use the FCR ring
I've tried equipping 2x BK and Relogging
I've tried Resetting his stats with FCR/STR Ring then Stat/ting him with 2x BK
I've tried way to many things could this just a bug or something along the lines of i need to invest 5 points into strength (i prefer putting 0 in)

 

Thanks, i never knew about Switching between CTA and your Main weapon... but it was working before and suddenly stopped idk why but anyways yeah i think i'll either switch back to Mara's or Invest those points into strength

 

get str belt, amul, ring and then equip eni and then get off that str items and thats all... if u die get that str items for equip eni
if u dont have enought str f.e. to CoA u need to put some str somewhere anyway..

 

i do this most times with a 10Fcr/19str ring tho i would prefer not to since it slows me down so i think i'll figure out how many points are required precisely and maybe buy skillers with str or put points into strength
