Bug: Teambuilder Exports sets involving Hidden Power in a format it does not accept when Importing

Teambuilder both exports sets, as well as tries to automatically import sets via buttons like Showdown Usage in this format, where Hidden Power has [ ] brackets around the type:

Zapdos @ Leftovers  
Ability: Pressure  
Hidden Power: Grass  
EVs: 4 HP / 252 SpA / 252 Spe  
Timid Nature  
- Thunderbolt  
- Hidden Power [Grass]  
- Baton Pass  
- Thunder Wave

However, importing a moveset fails when using this format, with this error in Microsoft Edge (and likely Chrome/Chromium)'s console:

storage.js?2d307af6:1250  Uncaught TypeError: Cannot read properties of undefined (reading '3')
    at Storage.importTeam (storage.js?2d307af6:1250:25)

Smogon's export format does not include brackets around the type, and these import just fine:

Zapdos @ Leftovers
Ability: Pressure
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Thunderbolt
- Hidden Power Grass
- Thunder Wave
- Roar

Teambuilder's import validation should either fix the error with reading brackets, or not add them at all
