Your problems mostly come towards the end.
1. As these are panel data, -tsset- must specify a panel too.
2. You have said that these are daily data presented as DMY, but they
look like monthly data in disguise.
3. Assigning a monthly format to daily data will not change it to
monthly data, as I often point out on this list. See e.g. the thread
starting at
