Tests are not visible

Hello

I moved several postmantests from my WIP-Collection to my personal collection and commit to it.

One of those testcases is a folder with several requests named by the number of the test: 2455. I can’t seem to find my test after I moved it to my personal collection, altough it seems like it found something:

My colleagues imported my collection after I commit it and can’t find it either. The only difference is, that they get absolutely no results where I at least find the folder I moved the testcases to:

Has anyone else had that problem?

Thanks for the help.
