How do i fix this sprite sheet problem?

[mike206]

So i'm very new to using gimp and i have version 2.10 and in this video clip you will see i'm trying to edit
this sprite sheet by replacing a section of it with another image. When i test in game all of the animations i didn't touch still move because i didn't mess with them but the area i cut out and replaced doesn't animate at all. Can
someone help me to fix this? Oh and i'm testing this in RPG Maker MV, Thanks 

*update* for some reason none of my video links worked. sorry about that so i had to upload the
video on my facebook game page so please check out the issue there, thanks

You replace 3 frames by 3 others that are awfully similar so the animation could be hard to notice.

Gimp isn't adding secrets bytes in the PNG and it doesn't know that the image is a sprite sheet. If the PNG is OK in an image viewer then the problem is elsewhere.
