"Ankipandas Conversion Issue: Erroneous Update Messages in Anki Database Export"

**Bug Description** When utilizing ankipandas to convert an Anki database into a pandas data frame, an issue arises where the 'col.notes' table in the flashcards displays the message "Please update to the latest Anki version, then import the .colpkg/.apkg file again." This message appears on both sides of the flashcard. Notably, this problem does not affect all Anki databases, but only specific ones. **Steps to Reproduce** To replicate the issue, follow these steps: 1. Convert an Anki database into a dataframe using ankipandas. 2. In the resultant dataframe, examine the 'nflds' column in the 'col.notes' table. **Expected Outcome** The expectation is the col.notes['nflds'] should be the content of the flashcards. **Screenshots** Screenshots should be provided if they will assist in illustrating the problem. **System Information** - Operating System: macOS - Version of ankipandas: 0.3.15 **Additional Information** I encountered this bug with a specific .apkg file, which I downloaded from [this link](https://ankiweb.net/shared/info/475916804).
