Upgrade to 12.03 and getting a Smarty3 hard error (on EditView.tbl)

I'm trying to run an upgrade from 11.0.6 -> 12.0.3 and getting a hard error in the upgrade wizard relating to a Smarty3 syntax error (and unable to convert)

I'm no developer and have checked for the suggested syntax issues from this URL:

Would appreciate some help, if anyone can assist, please.

(Module location is .\modules\Studio\DropDowns
