The Geometry is Not M-Aware

When using the Erase geoprocessing tool from the Analyst Toolbox I get the following error "ERROR 999999: Error executing function. The geometry is not M-aware Failed to execute (Erase)."

With small subsets of my data, there's no problem running the tool, but when I run it on my thing it seems to give me this error. If anyone is curious as to what I am trying to accomplish:

  1. - This is my original data (water features and another shapefile - both are polygon geometry)

  2. - And this is what I am trying to achieve. Delete all the water features from my original shapefile so that I can recalculate the area of my shapefile

I have tried the following steps to try and fix the problem:

  • Repair Geometry of both of my polygon shapefiles

  • Turned off M-aware under my environmental settings
