losing stats for no reason

while playing POE2 I will lose 18 to 20 strength and 10 dexterity when i get into a fight. i have tried taking off my gear and replacing it, changing passive nodes, turning my computer off and on, disconnecting from the internet and reconnecting. the only way i found so not to lose my access to my gems (skill/spells/support) is that i made a necklace to give me 30 str. i still lose the str but i dont lose my gems.

does anyone know what is going on? is it a glitch or what?
