Amazon EU charging for monthly storage fees

I am a relatively new seller , selling 4 different articles with low success. Recently i have been getting ridiculous amounts of amazon fees that previously were not charged to me. For example tax on amazon fba prime seller since 3 months i have to pay 46€ while previously it was 39€ as advertised on their page. Similarly amazon is charging me storage fees that are getting ridiculous at this point. Last month i had to pay 44€ this month got a bill for 87 and i dont understand how?! Plus its taxed as well. Also they are charging me for storage fees in countries like france and spain where my inventory isnt even located. I want to ask is this even allowed or am i in the wrong here? Please help
