Orthodontist accidentally put attachments on using aligner rather than template?

Orthodontist accidentally put attachments on using aligner rather than template. Is this a problem? My orthodentist used my aligner no 5 (Invisalign) instead of the template when putting on my attachments. I'm wondering will this impact on my treatment? The aligner was not damaged and I am wearing this now. His assistant accidentally gave him the aligner rather than the template during the appointment and it wasn't noticed until the end.
