Visa Bulletin states: "Section 201 of the Immigration and Nationality Act (INA) sets an annual minimum family-sponsored preference limit of 226,000. The worldwide level for annual employment-based preference immigrants is at least 140,000. Section 202 prescribes that the per-country limit for preference immigrants is set at 7% of the total annual family-sponsored and employment-based preference limits, i.e., 25,620. The dependent area limit is set at 2%, or 7,320."
The Department of State adjusts the visa bulletin monthly to ensure they stay within the statutory limits listed above. When you see the numbers move backward in a particular category, the Department of State has adjusted based on the actual or projected number of immigrants applying for immigrant visas. There's nothing wrong. It's just part of the process.
Because there are more applicants than there are visas.
