I’ve now corrected this across Aethera and all five Nexora variants and released 2.3.12 Rev 1.
Please delete the previously imported Aethera and Nexora styles from XenForo, download the latest Rev 1 package from your purchase, and import the styles again from the updated package.
There’s no need to use the Merge option on the old templates.
Sorry for the inconvenience, and thanks again for bringing it to my attention.
