Variables are not changed

Hello!
I have one problem.
when I change in base template (demo_ms_excel.xlsx) one word("Dynamic columns" -> "Dynamic columnss") all variables in first page wasn't change (on 2 and 3 sheets was change).
When I created mistake?

I resolved!
Fir personal template need exec $TBS->PlugIn(OPENTBS_SELECT_SHEET, 1) after load template.
