Carbon model ValueError with REDD scenario_ InVEST_3.7.0_x86

Dear all,
I ran Carbon model with REDD scenario_ InVEST_3.7, I got the error below. Could someone kindly help point out what am doing wrong & how I can fix it. Thanks for your help.

Hi there, the error is saying that any pixel value found in the raster must have an entry in the CSV carbon pools table, and redd.tiff has 15 unique pixel values that do not appear in that CSV table.

To resolve this you may want to reclassify your raster so that it only contains pixels with integer values that match those in the carbon pools table. And/or you may wish to add entries to the table. Many of those 15 raster values appear very large or very small, and may be meant to represent nodata. In that case you should also make sure there is a defined nodata value in your raster.
