Anchor to tab:
Please define individual ID’s for tabs. Once the Tab macro is inserted, the ID should be defined, which will act as an anchor tag. There’s no need to insert the Anchor macro explicitly to the body content of the Tab page macro.
On the page being linked to the Tabs page, please click Insert > Link > Advanced > Paste the full link of the page containing TABS followed by "#" and the ID of the tab to be linked.
