Found water on the new micro filter

[J2LTB]

I washed the Csl today. Though I'd check what pollen filter BMW fitted last week at oil service.
New Bmw filter fitted but a little wet underneath the centre wiper arm on the filter. A little bit of seal is hanging down from above. Can the wiper scuttle panel be removed with taking the screen out ? Can the seal be replaced ? Has anyone else had this problem ?
