I am sorry, "bug" may was the wrong word to express my issue.
After creating my product system, and after calculating I tried to export to excel as you suggested in the picture above.
This is the moment I get the Error on exporting to excel.
Unfortunately I cannot upload better quality screenshots in the comment section, however the errors from the log file are the following, by the following order <Thread - Level - Category -Message> :
" main - ERROR - org.openlca.app.App - Failed to load libraries from <openLCA./ julia "
" Java FX Application Thread - ERROR - org.openlca.app.wizards.io.DbImportWizard - datavase import failed"
" Java FX Application Thread - WARN - org.openlca.app.editors.parameters.Formulas - failed to evaluate 1e8 "
" Java FX Application Thread - WARN - org.openlca.app.editors.parameters.Formulas - failed to evaluate we "
" Modal Context - ERROR - org.openlca.core.database.DbUtils - failed to get the database version "
" Modal Context - ERROR - org.openlca.core.database.DerbyDatabse - failed to create database version "
" Worker-0 Export - ERROR - org.openlca.io.xls.results.system.Result.Export - Error exporting results"
After reading the error names again I get the feeling that i did something wrong while importing the database. Does this list make it more clear?
