Techs Can't See the "Techs" and "Tech Groups" tab in the Calendar Module (12.8.2 and Higher)

Has anyone else discovered that after upgrading to the last one or two versions of Web Help Desk (at least since 12.8.2), that the "Techs" and "Tech Groups" tab on the "Calendar" module aren't visible to TECHS with standard tech permissions?

I opened a Web Help Desk ticket on this back in May 2024 and the best I've gotten back is that we have a "failed install" and that there was no programming in place that would ever hide either of these tabs from any users.  As part of troubleshooting the issue, we freshly installed Web Help Desk on an entirely new server and an entirely new database.  The tabs appeared in the NEW system...but once we restored our database to that sever?

The tabs disappeared again.  I believe the issue is a table/database issue...but the Help Desk is sticking to their guns in this case and leaving my organization to the wind - its our issue...not theres.
With all the talented people here...is there anyone who's seen this and can recommend anything more useful than "Do a reinstall and start from scratch?".

That's definitely NOT an answer...and the lack of real support from Solar Winds in this case, is pushing my organization over the edge to look for a new product.
Web Help Desk doesn't get better with age.  It just keeps falling apart!
