After updating VEEAM Backup & Replication from v12 to v13 the button for selection months disappeared.
Below screenshot shows an example tape job with only runs at specific months. The button to get to the selection field is not visible anymore.
By accident I clicked to the empty space at the right position and the selection pop-up showed up, it seems the button is there but just not visible.
I hope that helps the ones having the same issue and Veeam to get it fixed.
Welcome to the forum.
I agree, something seems off — the UI element is there but not visible.
Thanks for reporting this; I’ll discuss it with our R&D team.
