Not able to use Date Modified In Subsequent steps in Pipeline

Good morning,

I am currently running a pipeline that is supposed to trigger when the date modified field is changed, Now in most parts this works but for some reason there is certain times the pipeline will not trigger even though the date/time has changed.

One solution I had was to create another step within the pipeline using a field of "Manual Date Modified" and timestamping it with {{time.now}}

By doing this I was going to a new filter of if Manual Date Field is before Date Modified then trigger the pipeline, However, it will not let me select Date Modified as a subsequent step.

This field is in built in field from Quickbase, Has anyone else ran into this issue previously? and if so were you able to fix it?

Thanks.
