import image: a new feature or a bug?

in HitFilm
Hi! 😊
With the new version of Hitfilm pro (15), there is something strange: when i import a single picture, i have this:
if i choose "import images", it's ok, and if i choose "import image sequences" i have a single picture which only lasts 1 frame (and impossible to increase the duration)
Can someone explain this?
Thanks

I’m guessing you may have grabbed the image from a camera or something and the file name was something like IMG_001.jpg.
This is a syntax used for image sequences, so it probably triggered HitFilm to ask if it was, in fact, an image sequence. This is probably a case where it’s best to simply click the “Remember my choice...” checkbox and use “Import Images”.
You are certainly right, I tested, but when these are pictures with numbers at the end, sometimes hitfilm asks, sometimes not.
For example, it asks nothing for IMG_001.jpg nor for image8.jpg, but for arc en ciel_3.jpg yes.
😕
strange....
It also does it for PNG files thinking they are animation frames. But I just choose import images. If you push sequence it will import all as a animation
