Importing png sequence problem

[WestwardJuly]

So I've been having this problem where some of the png images in a sequence are missing. When importing a png sequence from another software (Toon Boom Harmony) I faced this problem. 

So I attached some files to demonstrate the problem.

In a 24fps file I numbered every frame with a total of 68. I exported them as a png sequence and everything was alright until I imported it in AE in 24fps composition. Few images were missing, making the footage not 68 frames long in AE

I ended up finding the solution. Unfortunately, I can't take down the question anymore.
The problem was solved in Preferences > Import > Sequence footage. I just needed to change the frames per second value to the fps of my current composition
