The InBESTigators

This show currently has an 8.1 out of 10 rating on IMDB which is incredibly high for a children's show. Didn't watch a lot of episodes since it's really a kid's show, but as such a show it's really good. Basically Encyclopedia Brown with adorable Australian accents and recurring side characters which give this a bit more serial feel than a typical kids show (I'm looking at you Girl Meets World). Pretty much every episode ends with the "culprit" admitting it and saying they are sorry.
