Question halos and reflections

Hello,

I cleaned my eyepieces for the first time yesterday, when i went to use them last night, i noticed star halos and i could see out of focus reflections in the eyepiece aswell. I had never seen either of these things in the eyepieces prior to cleaning. I used the bintel UHTC cleaning solution to clean them.
This was also the first time i used my scope after cleaning the corrector plate with the UHTC solution, so i hope i havent damaged the coatings on the CP.
I read that the halos or reflections were from less than optimal lense coatings - but like i said i had sever seen it until after cleaning.

Could someone please help me to understand whats happened?
I hope there is just a thin film of something left on the eyepiece that needs to come off.

thanks
Josh
