Campaign copy keeps original blueprint SMS

I noticed a bug when copying a campaign created from a blueprint.

Steps: I created a client campaign from a blueprint, then edited the SMS content and the J+3 email.
The client has four locations, so I used the “copy campaign” feature to duplicate it to the other three locations.

Result: the copied campaigns correctly include the modified J+3 email, but the first message (SMS) was not updated and stays identical to the original blueprint SMS, ignoring my edits.

It looks like the copy works for all steps except the first template.
