The list of questions under 'stacks' grows very large after certain steps

[Prat-yush]

Steps to reproduce

Step 1: go to /roadmap page
Step 2: Go to 'Neetcode 150' dropdown
Step 3: Change to 'Neetcode 250'
Step 4: Change back to 'Neetcode 150' right after. Don't click anything else

Open 'Stacks' list.

The list has a lot more questions, most of them unrelated to stacks.

Same results of the question list is changed to 'NeetCode All' and back to 'NeetCode 150'
