(d) Except where the existence of a previous conviction of any subdivision of this section was not admitted or not found to be true pursuant to this section, or the court finds that a prior conviction was invalid, the court shall not strike or dismiss any prior convictions alleged in the information or indictment.

(e) This section applies not only to persons who commit any of the acts designated in paragraphs (1) to (6), inclusive, of subdivision (a), as a business or occupation, but also applies to every person who in a single instance engages in any one of the acts specified in paragraphs (1) to (6), inclusive, of subdivision (a).
