When Eastman Kodak stopped producing their own backing paper, they contracted that out.
Since then, they have had problems with some films, in some situations, in uncertain frequency. Reports of those problems were most prevalent in and around
2015 going into 2016.
The problem is called "wrapper offset", and occurs when the film reacts with the paper and ink on the backing paper. Ghost images of the numbers and "Kodak" may appear in your negatives. It is a problem that 120 film has always been susceptible to, particularly when exposed to high humidity and/or temperature, but the incidence apparently increased greatly with the then new backing paper.
Some films have had more frequent reports of problems than others. Many films either haven't suffered from the problem, or the effect isn't visible. The incidence of the problems might in fact be quite low, but the internet tends to do a wonderful job of integrating the reports of the problems that do arise.
The problems seem to be film type dependent - not surprising as it involves an interaction between film, ink and paper. T-Max 400 seems to have been the first where it was reasonably widely observed. I have seen some reports of problems with Ektar and Portra, but my sense is that there have been more reports from the users of the black and white emulsions.
T-Max 100 hasn't been available for quite some time because of the problem. It is a fair bit different than other 120 emulsions, and therefore seems to suffer more from wrapper offset. It may be that Kodak will need to re-design it.
Eastman Kodak have had their supplier revise the backing paper at least twice since 2015. There have been statements here on APUG/PHOTRIO from Ilford/Harman and others that there remains only one paper manufacturer in the world that has the capacity to manufacture the backing paper to the necessary high standards. A few years ago Simon Galley from Ilford confirmed that it cost them more money to buy the backing paper for a roll of 120 than it did to manufacture the film itself.
Avoid Kodak 120 film with 2017 "develop before" dates. There are lists of problematic batch numbers out there, but despite best efforts, they have become fragmented.
If you encounter this problem, it is important to understand that the only role that Eastman Kodak has with respect to still film is as a contract manufacturer, and their only customer is the separate UK entity known as Kodak Alaris.
Kodak Alaris are the people to contact for film replacement if you find you have problematic film.

With great trepidation, I refer you to one of my threads, where I tried to organize some of this information:
