Business Vehicle Depreciation - Older Vehicle not accurate

I have a business vehicle that I purchased in 2014.  I purchased a second business vehicle in December 2019.  When reviewing the depreciation amounts, I noticed my 2014 vehicle is less than 30% depreciated.  The software is telling me I'm in year 6 of depreciation and limited the depreciation amount to $1783 (which I think should actually be $1875).

Per the SW, my second vehicle qualified for $18,100 1st year Section 179 depreciation and looks like its on track to fully depreciate in 6 years. 

How do I "catch up" the depreciation on my older vehicle?

Thanks
