Issue with bundles product x bulk editor since updating woocommerce

Hello,
We updated woocommerce last week, since we meet a new issue with “bulk editor”:
When we edit Bundles products with bulk editor, and we save, even without modifying anything, the bundle product loses all its components, and is changed to unpublished product.
I contacted the developer of the plugin “bundles” (woocommerce), who refers me to you because he says that the plugin “bulk editor” is no longer compatible with the latest update of woocommerce, which causes the problem. Can you help me?
Thanks a lot in advance
