Issues With Buying Train Tickets on KOLEO - Adding Passengers' Names

I recently purchased three train tickets on Koleo from Warsaw to Gdansk for May 20. I input my name and the name of the other two passengers as there was an 'add' button to add more passengers. I proceeded to buy the tickets with no issue. When I later looked at the tickets on the app, all three tickets have my name on them. I expected to see my name on one ticket and the name of each of my two friends on the other two. I sent a message to Koleo to ask how to fix this. I was given an instruction to log into my account on www.Koleo.pl, then to click tickets > options > and change the name of the passenger on each ticket. First, despite choosing English as the language, subsequent screens after the main screen revert back to Polish. So, using Google Translate I found a page with a tab that says 'Tickets'. From there....I am lost. There is no 'Options' button. There is a tab to 'Change Name', but I am only able to change my name. I expected to see three tickets with a tab next to each which would allow me to change the names on the other two tickets. Has anyone had experience on Koleo with booking tickets for multiple people? I have never had this trouble when booking train tickets on another app for train tickets in France, Italy, etc. I just don't want a problem when we board the train. Thank you!
