BsPlayer dosent keep the screen aspect ratio

[Morm77]

I want to watch a series, and i want it to display at a 16:9 ratio, the original ratio is 4:3, so i change manually to 16:9, i went to setting and click on “remember window size setting”. But when the next episode starts, it goes back to 4:3!!
And i need to change the ratio again and again.. thats just not A 2020 problem, thats a 2004 problem... wtf??! How do i keep the ratio i want to play on every episode automatically??
