You should also bump the data version of the report here:

https://github.com/eth-cscs/reframe/blob/044397958f6cc6eba0a5272cd26dbbb03c0959d8/reframe/frontend/cli.py#L597

The idea is to bump the data format minor version every time we do an incremental change and the major version every time there is a breaking change.
