Why was A Twitch in Time released in Spring 2001 instead of Fall 2000 with different artwork?

The reason that I'm asking this is because it was advertised along with Zapped and Magical Adventure (both of which are based on The Animated Series).

If you look closely at the advertisement, you'll notice that on the game's artwork Sabrina's holding Salem in her arms while she's wearing a dark blue/purple dress and standing in a purple background. Another thing you'll notice is that in between them are two bubbles floating around with the words "Sabrina, The Teenage Witch comes to Playstation!" and "Coming Fall 2000!".

The advertisement was released in Fall 2000 when the show was in its fifth season on The WB.

For some strange, peculiar reason, A Twitch in Time was never released around that time along with Zapped and Magical Adventure. instead, it was released in Spring 2001 and the artwork for it was completely different.

If you look closely its front cover, you'll notice that Sabrina's holding Salem in her arms in the same position only this time the dress that she's wearing is pink instead of dark blue/purple and the background that she's standing in is blue with a clock and zodiac signs shown instead of purple with the floating bubbles like when it was advertised along with Zapped and Magical Adventure. Another thing you'll notice is that it includes is that above the front cover is the words "All-New Sabrina Adventure" with the a star above the "i" in her name and below it is the game's title witch an exclamation mark at the end.

Now don't get me wrong. I don't hate the game. I've owned and played it a dozen times then beaten it when I was younger. I also enjoyed watching the live-action sitcom that it was based on as well The Animated Series cartoon. I just find it rather strange and peculiar that it was never released the same time as Zapped and Magical Adventure and was postponed to a later release date as well having the artwork on its front cover completely changed DURING its release.

I understand that this may not seem important as both of the shows ended and the games were released many, many, years ago but I'd just like to know,.......is there any specific or particular reason as to why A Twitch in Time was released in Spring 2001 instead of Fall 2000 along with Zapped and had different artwork? Were there complications? Was it false advertising? Did the people involved in it not want to be released too soon? Did they have the artwork changed because they feared that it would've too similar to the one used on the front cover of Brat Attack?

Please let me know as soon as possible that all of my questions will be answered.
