I was confident but I later found out that I was wrong!

I had been using Kalita coffee basket type filters for a couple of years, thinking that they were manufactured in Japan, an usually reliable country. I thought I had to trust the quality of the product.

Two weeks ago, I was due for reordering 150 such filters from Amazon, when I found out by reading more about them,, that they were not made from paper but from polypropylene, a plastic. I discarded the several ones which I had left, and went purchasing real paper Melitta filters.

I don't see Kalita filters listed on Amazon. Did you by chance buy a compatible one?
I see here says for Kalita filter material: "High-grade paper stock."

To tell you frankly, I'm really puzzled! You say you didn't see Kalita filters on Amazon? I've just googled Amazon.com and I see them listed.
I did not invent the fact that I had read "manufactured from polypropylene". Unfortunately, I already discarded the few remaining ones which I had.

Are you using a VPN? If it's possible to choose a Canadian server, you should then be able to see those Kalitas. Actually, the ones that I was using felt like real paper. What I suspect is that the currently produced ones are made from paper, and the plastic bags that contained them would have indicated polypropylene at the time. But I doubt that it was to indicate the container material as such.

I was using the KWF-185 filters.

Ok, I found the KWF-185 filters. It seems a few other reviewers mentioned issues with the filters:
It may be an issue with fake products, which are unfortunately very common on Amazon.
Some reviewers mention print color on plastic packaging is different (green/blue text) - could also indicate this

The Melitta basket type filters for 2-5 cups also are a lot cheaper. From now on, I'll stick with them.

I finally decided to get a permanent stainless steel filter which was designed to fit with the OXO 8-cup coffee maker that I have. I am satisfied with the results and I no longer need to purchase paper filters.

The advantage with a permanent filter is that you get to taste the cafestol which is filtered with a paper. So you obtain a stronger flavor using the permanent filter. The possible drawback is that this cafestol would increase blood LDL cholesterol. Of course, the effect would depend on how many cups you drink on a daily basis.That's not a problem in my case as I show the advantage of having a Gilbert's syndrome condition. This is a harmless, inherited liver condition where the liver doesn't properly process bilirubin. This is a very powerful endogenous antioxidant which prevents oxidation of bad LDL particles that cause atherosclerosis.
