It would seem from the tone of your question that you are referring to Lightroom Classic. If that is the case then you need to remember that the adjustments you have made are stored in the catalog and have not been applied to the images UNLESS you have chosen the option to write changes to XMP in the Lightroom preferences. That means that if you cut and paste those images from the scene drive to an external hard drive the Lightroom catalog will lose track of where the images are located. In other words, you haven't learned how to use the Lightroom catalog properly. You should either move the images within Lightroom so that the catalog can keep track of where the images are and therefore keep all of your editing intact, or, the instructions in this tutorial on how to realign the catalog after you have moved images not using the Lightroom catalog.
