Image upload set to 1px where to change

Hi I am using a script I bought on codecanyon but the dev seems awol, the script has a news page creator which uses an image upload however - the image is getting resized to 1 x 1px despite setting the dimensions - see the screenshots Screenshot_5 I am limited to one screenshot

I am running Yii 2.0.38 with the following extension 2amigos/yii2-tinymce-widget

Anyone experience a similar problem, it looks like the script is uploading 2 copies of the image but they are both getting resized to 1 x 1

I am new to yii so please let me know what source files I should post
