@AntonM97 thanks for reporting it! This is a tricky one, it will take me time to reproduce.

Import is one of the most complex parts of Flowkeeper's inner logic, with lots of corner cases. Even though it has some 86% unit test coverage, apparently even this still doesn't test all of those corner cases :(

The only thing I can suggest in the mean time is try ticking the "Ignore errors and continue" checkbox when importing. This error should be an isolated problem, so the rest of the data should import correctly.

Also, if you are using export/import simply to transfer the data file between two computers, you can just copy the data file itself (see Settings > Connection > Data file).
