Issues with Editing Clay Search and Comparing Results to LinkedIn

Hi all, I’m wondering if anyone can help me with the following: I created a “Find People” search in Clay, using specific companies as inputs to build a table. However, when I try to go back and edit the inputs — specifically to add more companies under the Company tab — it doesn’t allow me to make any changes. Does anyone know why this might be happening? Also, I ran a like-for-like people search in LinkedIn Recruiter to compare results, and I noticed a huge difference in the number of people found — the LinkedIn list is significantly larger. Am I missing something in how Clay sources or filters people? Thanks in advance for any insights!
