The right-column Custom HTML block re-displayed the vendor name a
second time. In the source Purchase Order design that block was part
of an address card (name + mailing address together); Request for
Quotation has no per-supplier address field, so after dropping the
address the block became a bare, purposeless repeat of the name
already shown at the top of the left column. Classic, Modern, and
Modern with Images each show it once - Bordered now matches.
