incompatible annotations with provided labeling schema

[OverFitted]

Describe the bug
Labeling scheme is giving "Created annotations are incompatible with provided labeling schema, we found: 12101 with ..." which is impossible as I only have:
Tasks: 10436
Annotations: 1186
Predictions: 1497

The project's labeling schema was working perfectly fine at least one month ago (I'm not sure, if label studio was updated during this time period)

To Reproduce
Steps to reproduce the behavior:

1. Go to project
2. Click on "Settings"
3. Click on "Labeling Interface"
4. See error

Expected behavior
Labeling scheme rendering properly

Environment (please complete the following information):
