Tab page is closing when deleting buffer

Question

I'm using bufferline.nvim in order to display both buffers and tab pages on the tabline, whenever i delete a buffer with bd, all the buffers on that tab page are deleted as well, alongisde with the tag page itself, it looks like this:

If i recall correctly, when deleting a specific buffer, only this buffer should be deleted and the tab page should remain opened alongside the other buffers that were already present on that given tag page

How do i prevent such behavior from happening?

Issue solved on r/neovim:

A tab will close when the last window is closed. A window will close when the buffer currently occupying it is deleted. This is default behavior. Tabs are collections of windows, that's how Vim handles them, if you want to keep a tab open you must have one or more windows for that tab
