Release clipping masks option gone from right click options menu?

I deal with line art drawings exported from Seimens NX cad software on a daily basis. In order to select the various views on the page, I need to release a clipping mask that is added upon export. I have always done a select all, right click, select ungroup from the popup options, then right click and select release clipping mask from popup options. After updating to illustrator 28.7.1 last week, the option to release clipping masks is gone. Where did it go and how can I get it back? There have been no changes to the cad software as they are major updates and the entire company is made aware of changes and updates to the software.
