All radiomic features show blank after renaming a segmentation

In slicer radiomics, I find an issue below.

Step 1. Make a segmentation by segmentation editor.
Step 2. If change name of the segmentation, all radiomic features show blank and cannot be calculated (there is no problem before renaming the segmentation).

Could you tell me how to solve this?

Thanks!

Please see the attached figure.

The green segmentation named Segment_1 (default name) can calculate radiomics features, but the yellow area named ROI (renamed segmentation) cannot.
