Back button at offering level bring me to a different result

Hello,

Searched for offerings for a course and on clicking the particular offering title, it leads to its details and if I would like to go to another offering and press back button, the earlier search result goes away and I have to redefine the search criterion. I don’t want to set this specific search as my default search. Is there any way out.

Did anybody notice the same issue?

Thank you

Alessandra
