Windshield Wipers not working correct

[Beb]

Hello,

this time i have the exact opposite problem than my other ini planes have. When i turn on my whipers in the A350, the rain is being whiped away, but the whiper itself isnt moving. I mean its better than the opposite, when the wiper is moving but you still cant see the runway but i think its still annoying and really kills the immersion when flying in bad weather conditions. I attached a video so you can see what i mean. (Sorry for the bad quality but i can only upload 7mb vid and you an still see the point
