With nothing selected, press Cmd/Ctrl+B to open the Text Frame Options dialog. In the Vertical Justification section, set Align: Top, (assuming Top is what you want). This won't change any pre-existing frames, but all subsequent ones should default to what ever you set.
If there are pre-existing frames you want to change, select them and do the same.
With nothing selected object>text frame options. Probably set to bottom
there. If not, check your object styles.
Most likely the Basic Text Frame object style if objects from the library are changing, too.
Thanks everyone, that did the trick. Even fixed all the already poured columns that were defaulting the wrong way
