I have a table which I did for my MSc thesis, that worked just fine:

However, now I want to use that table for an article. I have copied the code, but the bullet points from the 2nd column are too close (vertically):

Any idea how I can fix this? I have tried some things suggested at StackExchange, but none of them worked.
This is the code for a test document (where the problem does NOT stand):

I can't provide a full compilable code, given that I'm using a template from the Sensors Journal (https://www.mdpi.com/authors/latex). However, you can download my full compilable code here: https://ufile.io/n7pg8

Many thanks!

result tested on overleaf gives the following result:

In MWE above i made some off-topic changes which (according to my taste) made table more nice (use of tabularx for table environment, makecell for more vertical space above and below cell contents).
