Hi there! I’m experiencing some really strange behavior from NLP. I was scanning some normal Portraits 160 35mm film using my Sony A7iii, in a Mac. I’ve imported all the RAW files from from roll to LR, cropped and set the white balance. When converting all the frames it gives me insane results - totally blown and crazy colors. But when I convert it one by one it works fine, until I want to edit it again (with NLP) and it somehow jump back to the bad result even though I didn’t even change anything?… Beside that I experience all kinds of unexpected behavior such as sometimes I’ll try to un-convert an image and it will get “stuck” in the positive form, but NLP will tell it needs conversion. It looks like something got wrong with my software. Should I uninstall and reinstall NPL, or any other solutions? NLP became unusable and I really hope to find a solution… Besides that - another unrelated issue is that I was trying to convert Santa Color and got really bad results. I know the base is different and that throws it off, but is there a way to still get decent results with NLP? I got perfect results using the same Raw files with manual conversion in PS, so it’s not the scan/files. Thanks in advance! David. ---

Hey – Welcome David! I’ve no experience with Santa Color, so can’t comment on that. As for NLP and Lightroom behaving weird, I had this issue in the past too. What fixed it was to “Restore preferences to default settings” in LR. Here’s how: > **[Set preferences for working in Lightroom Classic](https://helpx.adobe.com/lightroom-classic/help/setting-preferences-lightroom.html)** > > Learn about setting preferences to change the Adobe Photoshop Lightroom Classic user interface. ---

> [@rossdave](#): > > When converting all the frames it gives me insane results - totally blown and crazy colors. > But when I convert it one by one it works fine, What version of Negative Lab Pro are you on? Make sure you are on V2.4.2. Some of the behavior you are describing sounds like a bug with batch conversion that was in v2.4.0. And as @cvandebroek suggested, it might be a good idea to reset your Lightroom preferences prior to running the update installer. -Nate ---

Thank you both for your helpful tips! I somehow missed the fact there was a newer version… I’ve reset LR and updated NLP and from a quick glance it looks like it did the trick 🙂 Thanks again! David. ---
