Transparent line on the left side after editing image

[Davit]

Hey,

I am new to photoshop and this might even be a silly question.

Every time I am done editing my images they get transparent line on the left side. I am interested whether there is something wrong with photoshop or its me doing something incorectly? 

Here is the image that shows the problem

How did you edit this image? Can't tell that it's transparent - a screenshot in PS would be better. Looks rotated or cropped.

Like Melissa said, there seems to be something askew with your image. This happens with every document?

Thanks for a reply.

Unfortunately, I have not saved the psd for this one as it was not worth it. It happens quite randomly. Maybe it is not visible on the image but it is truly transparent.

It happens with most of the images and I have to correct it manually. I just use basic editing steps, but still get this unusual transparent line on the left side.

The only steps that might influence it could be selection/masking/lens blur or simple cropping
