I think the SAGA Description file for Raster normalization tool is not properly configured. (Each Description file defines the UI settings of SAGA tool in QGIS processing environment). **Based on QGIS 3.22.3** (1) Try and find `grid_calculus_grid_normalization.txt` in QGIS installation folder. > In my QGIS3.22.3 on Windows10 environment, the Description file is located in `"C:\Program Files\QGIS > 3.22.3\apps\qgis\python\plugins\sagaprovider\description"`. (2) Open the `grid_calculus_grid_normalization.txt` by any text editor application (e.g. Notepad++). You will probably see four lines: Grid Normalization grid_calculus QgsProcessingParameterRasterLayer|INPUT|Grid|None|False QgsProcessingParameterRasterDestination|OUTPUT|Normalized Grid (3) Then replace it with below: Grid Normalisation grid_calculus QgsProcessingParameterRasterLayer|INPUT|Grid|None|False QgsProcessingParameterNumber|RANGE_MIN|Target Range (min)|QgsProcessingParameterNumber.Integer|0|False|None|None QgsProcessingParameterNumber|RANGE_MAX|Target Range (max)|QgsProcessingParameterNumber.Integer|1|False|None|None QgsProcessingParameterRasterDestination|OUTPUT|Normalised Grid (4) You may notice you have just added line4 and line5. Save the file (you may need writing permission to do so). (5) Restart Raster normalization tool, now you will have `Target Range (min)` and `Target Range (max)` in the UI window (See below).
