drop down in shape layer missing size, position and roundness options?

[snowdogghask]

hi there! so in a tutorial, i'm trying to add an expression to "size" under the rectangle path 1 drop down. my rectangle path 1 drop down only has path instead of "size, position, roundness" like seen in the tutorial. what should i do? many thanks in advance!

Your Rectangle 1 shape has been converted to a Bezier Path. It needs to be a parametric shape. There will be no Path property in a Parametric Shape.
