Audacity is automatically adding silence to my tracks

I haven’t used audacity in a while, it looks different now so I’m assuming it upgraded itself.
I’m having an issue i never had before. When I export audio it keeps adding a small moment of silence before and after the song.
I’m trying to make a song that loops and it’s not possible anymore with this happening.

Here’s a pic. The top is what I exported, and below is what the file looks like after exporting.

Don’t use MP3 for loops. Use WAV, OGG, AIFF or FLAC.

You’re right! It’s not that audacity changed, I just forgot how to use it lol
Thanks for the help!
