What is the bug or the crash?

plugins\QNSPECT\processing\algorithms\modify_land_cover\modify_land_cover_by_nlcdccap.py", line 124, in processAlgorithm
land_cover_name = self.choices[enum_value]
KeyError: 44

The 'KeyError' number refers to the type of land cover I ask for after the modification.
Since I am using the NLCD Land Cover, the KeyError starts from 26 corresponding to the NLCD class 11 (Water) and goes up to 44 - the last class, 95 (Emergent Wetland).
It seems like it is unable to fetch the NLCD land cover value provided in the tool.

Steps to reproduce the issue

Get NLCD Land Cover for any extent. (I used Curve Number Generator Plugin to get a small area).
Create a vector Area of Interest covering a small portion of the land cover.
Run the 'Modify Land Cover (NLCD/C-CAP) processing tool in the 'Data Preparation Section' of QNSPECT.
Those are the only two input files required. The final input is an option asking for the desired land cover through a dropdown list.
Run and the posted error will be seen.
