Stamp on new screen

[Lycel]

Hello all,
I got a new screen a few months ago for my Dell Latitude laptop, after accidentally breaking the screen. I got it ordered and installed through a local computer repair shop, because I did not trust myself to do so. However, immediately after I got my computer back, I noticed a stamp-like mark on the bottom left of the screen, an upside-down "BF". It doesn't come off from light fingernail scraping, and I'm too scared (especially after breaking my last screen) to try anything more.
How can I remove it, if I can at all?
Some pictures of the stamp (might be tricky to see):

Info about the computer: Dell Latitude E7240, a shiny screen (the broken one was matte),a bit over 31cm diagonally. Not sure what else you might need, but feel free to ask.

Thank you
Lycel

There's usually a thin plastic film covering the screen that has these type of figures printed on them.

Remove the bezel so that you can peel off this plastic. No need to completely remove the screen.

take it back to the store to have them do it as they should have removed that film before the bezel was put back on.

Yes, there was a plastic film over the screen. To save time and money (mostly time as I would have made them do it free), I removed the bezel myself and the plastic thereafter. I was a bit scared for my laptop to be honest, as I'm no expert in hardware, but it went through without a hitch. I just used a thin, flat, flexible plastic knife to pop off the bezel, peeled off the plastic, then pushed the bezel back into place, no harm done. If someone else is planning on doing the same as me, look up how to remove the bezel on your own laptop (it might be different).
Thank you very much for your answers, and I am now enjoying a beautiful MATTE screen (no more shiny plastic, haha)
