Created attachment 188432 [details] floating table which spans two pages Open attached document. It has a floating table which spans two pages. Open the Navigator. You see "Table1" in Tables section and "Frame1" in Frames section. Save the file to odt and reopen the odt file. Look in Navigator again. Now there is an addition "Frame11" entry in Frames.
Confirmed, this is an ODT export bug. The internal SwDoc::mpSpzFrameFormatTable only contains a single frame, but the ODT export result has two <draw:frame>, which is not expected.
