I used Hasselblad 1600 copy Kiev 88 with old sort of films and may be another 1 million used them , their film backs havent got even an red window and you can touch the backing paper and yes , for your all single advance , you must open the small window and calibrate the advance. There is no light leak , may be an roll waited in high humidify refrigirator or high heat or not fresh film including these cheap films make the backing paper numbers ink dissolve and impregnate in to the paper and make a semi transparent material like polymer reinforced glass.
I think you may be right. Since the markings and numbers are evenly the same 'exposure' on the negative, I'm thinking the ink rubbed off onto the emulsion. Also the numbers aren't reversed if that makes a difference
Just because it never happened to you doesn't mean it can't happen to someone else. I've had it happen with Foma and Efke film with both a Zeiss Ikon Nettar and a Kodak Tourist.
Yup Tom, me too! I knew better, but took a chance with an old folding Zeiss camera a short while back. Efke film in that camera and several frames had some faint numbers on them. So, yes it does happen. Might not be the case with the Lucky brand film, but I can't believe they would continue to use the same paper/ink if it were a bleeding problem. JohnW
I took the backing paper and reattched the negatives to it, and iscovered that the images of the numbers appered where the numbers actually touched the emulsion, in other words they were offset to where light comming through the back of the camera could cause them to appear.
Avoiding this sort of trabsfer is the reason that has been given for the Light coloured print on Ilford roll film.

If DE is Delaware and if I am an Geography Bee , You are living at Atlantic Coast and some places have very high humidity.
If the markings have same exposure , I think paper printed its ink on to your film. What is your camera by the way ?
I wish you the best luck ,changing your film and supplier would change everthing.
Quite possibly humidity. They were stored in the fridge until we moved and haven't been put back in. I'm thinking moisture caused the ink to transfer onto the emulsion.
It's easy to tell if it's caused by light through the window or by ink transference. If the number appears in the same place on the negative as the window is relative to the film gate (i.e. the centre of the frame for 6x6) then it's light through the window causing it. If it is offset by about an inch, it's ink transference (or reaction) to the emulsion.
