Leaking shower screen silicon help

[kalmap]

Hi,

We've just had a new bathroom fitted, minus the painting which is why the below still looks a bit rubbish. But there is a problem with the corner of the screen leaking.

Inside the shower it looks like this, which appears to be correctly sealed? ibb.co/ysW2nXr

However putting water in the highlighted area, makes it run out the front of the frame shown here: ibb.co/ZgCfH54

What's the likely cause here? I'm guessing I cant just silicone the small bit on the front as the water is still getting in there, below the top level seal somehow and will just go elsewhere?

Thanks!

Has the frame been cut too short?
I can't really make out what it is but I'm assuming the creamy coloured frame is the outside of the frame which is silver on the inside?

Most likely need to put sealant right up the inside corner the whole height of screen

Yes that. Seal the inside frame

Thanks guys, I didn't think you were supposed to seal both inside and outside the frame? It does look like that will solve the problem as long as it's ok to do.

Our shower isn't sealed on either side up the long sides and water doesn't go through but I don't know how it's sealed.
