I have some layers containing DAT,MAP and TAB files, when I loaded these layers into QGIS some layers have check boxes before layer name and some layers won't like showing in below image.
In the above image you can see that boundary layer have the check box and compare_layer shows a icon instead of check box.
Now the problem I am facing is I am not able to delete the features from the compare_layer table and also from the layers similar to this kind.
When am trying to delete a feature from the this layer table and trying to save the layer, it throws an error like Could not commit changes to layer and compare_layer: OGR error deleting feature 15:
How can I solve this issue?
