New tab created automatically when applying a style

I want to have the first tab stop in style Heading 4 a bit further out
than its default - at 1.65cm rather than 1.52cm.

If I edit the style definition, create the new tab and clear the
original one, it saves fine. But if I e.g. use the format painter to
copy the format of a Heading 4 paragraph and apply this format (style)
to another paragraph with the same format, the whole underlying
definition of the style is altered and the original tab re-introduced!
I don't have 'automatically update' checked, by the way

I tried creating my own style based on Heading 4, but the same thing
still happens with that. The earlier tab always seems to want to
creep in. Does anyone have any ideas why?

TIA.

I found out why, in case it's of use to anyone: the tab stop keeps
being re-introduced by Word because the paragraph is numbered, and in
Styles/Numbering/Customize/Text position there's a parameter 'tab
space after...'. This causes a tab definition to be inserted into the
tab list - slightly skewed logic, imho, but there you are.
