Toon Boom Harmony Glitch export with weird framerate

Hello, I just exported an animation with 25 fps and the video has a reaaally weird framerate. First it’s going too fast and in the end too slow, even if in the display looks fine. I checked the scene configurations: It’s on 25 fps. I don´t know what to do please help :c

In the Motion section, choose a Frame Rate from the list. By default, it will be set to match the frames-per-second (fps) of your Harmony project. If you choose a lower frame rate, your export play back will be faster than your actual project.
