[Grammar] "had increased" or "have been increasing"? (problems)

“Recently, my problems had increased.”
“Recently, my problems have been increasing.”
In the last two weeks many problems have accumulated overnight.

Would you be so kind as to tell me, which one is correct?
Thank You so much!

I think the present perfect instead of the past perfect should be used if "recently" is used.

Not a teacher.

Both are correct. If you expect that they will continue to increase, then the continuous form is appropriate.

I'm not sure why you're asking about the past perfect and the present perfect continuous. This is putting two significant differences in the sentence. If you want to compare them, you should make only one difference, eg.
“Recently, my problems have increased.”
“Recently, my problems have been increasing.”

I think Barb might have misread your first sentence for the present perfect. If she did, I agree that they are both present perfect simple and continuous are both correct. “Recently, my problems had increased” is not correct, given that there's nothing to suggest that the past perfect is appropriate here.

Indeed I did. I assumed it said "have" and therefore "saw" it that way. Sorry about that!
