### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Paimon version 2.0 ### Compute Engine sdk ### Minimal reproduce step 1. Create a table with row tracking, Data Evolution, and two dedicated vector columns: `v1` and `v2`. 2. Insert rows with both vectors in the same file, with `v2` initially NULL. 3. Update only `v2` to a non-NULL vector, producing a separate vector file. 4. Read the table, including `v2`. ### What doesn't meet your expectations? Expected: `v2` returns the updated vector, while `v1` remains unchanged. Actual: `v2` still returns NULL from the older file. Existing non-NULL values can also remain stale after updates. ### Anything else? Column-group ordering can take precedence over file sequence numbers. The latest provider needs to be selected per field and row range; sorting entire groups by their maximum sequence is insufficient. ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
