Import in Imaging system 1.5.1 is failing with etlautomation script

Import in Imaging system 1.5.1 is failing with etlautomation script for the Application CSV's whose name contains decimals.

Example: Please see the below import log where the Imaging system is looking for the name RiskMeter_2_is_lnk.csv  where as the name of the CSV files is as below 

Log:

{"level":"info","msg":"Import: verifying CSV files for: RiskMeter_2","time":"2019-05-08T01:01:37Z"}
{"error":"filesExist: error checking file: exists: file does not exist: ../neo4j/import/RiskMeter_2_is_lnk.csv","level":"error","msg":"Import: file mismatch: filesExist: error checking file: exists: file does not exist: ../neo4j/import/RiskMeter_2_is_lnk.csv","time":"2019-05-08T01:01:37Z"}
{"level":"error","msg":"Import failed!","time":"2019-05-08T01:01:37Z"}

Screenshot:

The Workaround here is to manually rename the files from  Riskmeter_2.0 to Riskmeter_2 and then perform the import action.
