Type 1 Humalog? From tresiba

Can anyone give info on humalog. I was changed to tresiba, from levimir due to being discontinued, had trouble with that as continued stacking, whatever I tried. Have now been changed to humalog as a long acting, but looking this up humalog seems to be a fast acting insulin am confused as my dsn said it was long acting lasting - hours ? Can’t ring in yet so just seeing what people think/know ? Thanks

Thanks for that just confirmed my suspicions and dsn was hugely apologetic she had clicked on a half unit pen and it was the wrong insulin luckily she was in work today or by next week god knows where I’d be. Thanks
