Adding entries via form doesn’t work

Hi, I’m having issues with adding entries. I was able to import a css (although i found it odd that I couldn’t choose which form I wanted to import to, meaning every time I upload a csv it’ll create a new form, so I can’t add additional entries to the same form by just uploading a new csv.)

So I tried adding additional entries through the form, but they don’t show up.

Any ideas why this is happening?

Thanks!
