The reason you have a positive number in "corrent depreciaton" and a blank or zero in "prior depreciation" is most likely because you incorrectly entered an "in service" date each year, of that tax year you were working on, with the exception of the first tax year that asset was "actually" placed in service.
Look at the 4562 for 2017. I fully expect the in service date for that asset has a date in 2017 in it. Then look at the 2018 form 4562. TI bet the in service date is a date in 2018. That would be wrong. Same for 2019 I expect also, which is wrong.
Basically, if the 4562's for 2017, 2018 and 2019 have a zero or it's blank in the "prior depreciation" column for that specific asset, that's because you told the program you placed that asset in service in "that" year. So am I right here? If not, then what is the in service date for each tax year on that asset, in the "in service" column for that asset?
