Mercari weirdly skipping a month

Use Mercari mostly for buying stuff. Never had problems paying it off yet but…

I paid off everything that was due in February’s 後払い (stuff I bought in January) 2/27. Now I t’s the 1st of March so I get the usual red notification mark in the “Yaru koto list” and it says the usual “メルペイから3月の請求があります3/31までにお支払いください” but when I tap this, very weirdly only shows me the seikyu for 4月 due 4/30, which ofc is still zero since I haven’t bought anything in March yet.

I can’t pay a bill for zero yen wtf

And I know I bought stuff in February that I need to pay off, like 2man worth. But I cannot find this seikyu page of February items I bought that I should pay by 3/31.

The current notification is labeled in my yaru koto list as 3月, but when I click it, it’s showing a bill for 4月 and showing zero.

Im worried there is a bug going on. Has anyone else noticed this?
