I have encountered the bug when I try to rebalance the split of train/valid/test to generate a new version. However, I’m unable to rebalance the split after I click the button “rebalance”, drag the bar and save the setting. At the beginning, it can only reduce the ratio of train set, now I have reduced the train set to 0%, and I can’t enlarge the train set anymore, which also means the split setting can’t be changed any more.
