Similarily, if I knew that you have this problem only after sample injection and whether you have an equilibrium problem or not , I would not have asked what a ACN/H2O wash does prior to injecting sample.

For my knowledge, the BEH C18 column and the BEH PST 130 C18 are the same stationary phase. Waters declared that they produce a BEH 130 C18 material. Then they perform a test for the requirement for PST (Peptide Separation Technology). If the test is passed, the column becomes a BEH 130 PST C18 column. If the test fails, the column becomes a "normal" BEH C18 column.
