Since the rollover was to the plan of a different employer, I suspect that the rollover was to another 401(k). Hopefully this rollover was a nontaxable rollover to the traditional account in the new employer's plan because a rollover from the traditional account in one employer's 401(k) plan to the designated Roth account in another employer's 401(k) plan is not permitted. A rollover from a traditional 401(k) account to a designated Roth account in a 401(k) is only permitted to be done in-plan.
Check with your new employer's plan to make sure that the rollover was deposited into the traditional account. Perhaps only your new contributions are going into the designated Roth account.
