I speak a couple of languages in which there is no continuous present, but rather they use phrases such as “I sit and study Swedish” to mean “I’m studying Swedish (as in right now, that’s the task I’m doing)” or “I am in the process of reading a book”. They don’t change the form of the verb to highlight this continuous aspect, so perhaps they aren’t used to it.

Add to that that the continuous aspect in English is surprisingly complicated and arbitrary. If you try to nail down rules for how and when to use it, you might struggle. 😉 Folks struggling to use it correctly might be overcorrecting or merely confused.

There are, I’m sure, other reasons, but this is enough to account for some of what you’re seeing.
