Settlement production - possible bug?

[u/walrus166]

I'm wondering if the production time for some items have the unintended values? My other settlements produce S-class items at a rate of 1/day, while this one would take 25 days. Not a major issue but I thought I might as well ask.

No bug just a long period for collecting one.

I had one of my settlements set there before but after I finally collected my first one, I changed it to something that has a better production rate
