No running animation in Roblox, although it works in Studio

Okay, here I have an animation of running and this is what running looks like in Studio and what it looks like in Roblox

If anything, here’s where the animation itself is located

So, let’s start with the fact that I do not play all the animations in Roblocks, but again, I decided to start with running, as it is made through playing animation, not through its replacement in animate. What do you think could be the problem? (I created the animation yesterday)

This is a problem ever since animations went private, studio plays animations made by anyone, but roblox only plays animations that are:
• Uploaded to the group the game was created in
• Uploaded to the owner of the game (for non-group games)
• Uploaded by the roblox account (UserId 1)

If this is a group game make sure that the animation has been uploaded to the group, not your personal inventory.
