Save for web - photoshop 2024 for windows 11

Hello to everyone.

I'm having problems saving jpg files with save for web in photoshop. With de document sliced I'm unable to save slices in jpg format, it always saves in gif format even though I configure the settings for jpg and save those settings. The only way to make it work is by selecting all the slices in the save for web menu. This is annoying because I used a script that automatically saves all slices in different .jpg files and now it is useless, without making that selection. I was working in the 2023 photoshop. 

Is it going to be fixed soon? or is there any solution?

Thanks in advance
Marco
