When you add a step to a project, LabVIEW SignalExpress selects
input signals based on the signal types the step can accept. For
example, the Interactive Alignment step can operate only on
time-domain waveform signals. Therefore, the step selects as inputs
the last two time-domain signals created in the project. To change the
input signals for a step, select different signals from the pull-down
menu of compatible signals in the Input/Output tab of the Step Setup
dialog box.

Try to align the rising edges of the two signals by dragging a signal
within the graph. Click a signal to set an anchor point and press and
hold the <Alt> key to stretch the signal around that anchor point in the
x and y directions.
