Character Sprite made in Aseprite has white background despite file being shown as a transparent png

[Voltwolf56]

I haven't used much of 2k3 yet so I wanted to give it ago and made a pretty basic sprite sheet, with the correct dimensions, in Aseprite of this smiley face guy:

When I went to put it in the folder to use it, the thumbnail in the database was just completely black and then came up as an "unsupported png" so I went ahead and switched it to index colors in Photoshop to which the sprite finally showed up with its full animations but now it has a white background that takes up the rest of the sprites dimensions even when in game. Once again, its showing up white despite it being a transparent png even after index mode was applied. Did I import it the wrong way? or did I index the colors incorrectly?

when you import the image, click on the background part

^ This. Use Tools > Resource Manager, select CharSet from the list on the left, click Import, select your file, then the "Set Transparent Colour" window will appear, where you can click the background as mentioned.
