admin panel stays rtl while selecting English as main language which is ltr

Hi - I am running a Persian Blogging website which is rtl by default and I've been using Who Sees Ads plugin for a while, but recently I noticed that the blogs which choose English as their default language which is basically ltr, the admin panel would stay rtl because of this plugin. When I turn off this plugin, things work fine.

Any idea how to fix this?
