tooltips won't stay on

LibreOffice 5.1.3.2 with build ID 644e4637d1d8544fd9f56425bd6cec110e49301b
on Windows XP Professional 2002 Service Pack 3.

Each time I start LibreOffice the tooltips are off and I have to turn them back on: it won’t remember the setting.
Is this a bug or am I missing something here?
More importantly: how do I fix this?

5.1.3.2 works for me (shows tooltips) on Win10 normally, without need to enable a setting each time. You might need to reset user profile.

If it doesn’t help, then you could consider dropping the ancient version to try a newer one (the last that supports XP is 5.4.7.2). And even failing that, it beats me to understand why would one want to use 5.1.3, when there is a newer in 5.1 series (5.1.6.2)?

oops. should be the answer…

Resetting the user profile cleared the issue, thanks for the suggestion.
As could be expected, it also cleared the extra icons and toolbar changes I made over time (sigh)…
