Could not switch Tab Sheets on a window

I have following items of an application written in Delphi, printed with print_control_indentifiers and I want to select the tab with title=“Units”:

TfrmExportSetup - 'Export Setup'    (L0, T0, R400, B600)
['Export SetupTfrmExportSetup', 'TfrmExportSetup', 'Export Setup']
child_window(title="Export Setup", class_name="TfrmExportSetup")
   | 
   | TPageControl - ''    (L6, T29, R394, B555)
   | ['TPageControl', 'pnlExportActive1TPageControl']
   | child_window(class_name="TPageControl")
   |    | 
   |    | TTabSheet - 'Maintenance'    (L10, T53, R390, B551)
   |    | ['MaintenanceTTabSheet', 'Maintenance', 'TTabSheet', 'TTabSheet0', 'TTabSheet1']
   |    | child_window(title="Maintenance", class_name="TTabSheet")
   |	|
   |    | TTabSheet - 'Units'    (L10, T53, R390, B551)
   |    | ['UnitsTTabSheet', 'TTabSheet3', 'Units']
   |    | child_window(title="Units", class_name="TTabSheet")

I tried different methods and none works. Some of the failures:

1.
Code:
self.export.child_window(class_name="TPageControl").menu_select("Units")
Error:
pywinauto.controls.menuwrapper.MenuInaccessible

2.
Code:
page_control = self.export.child_window(class_name="TPageControl")
page_control.child_window(title="Units", class_name="TTabSheet").click_input()
Error:
pywinauto.findwindows.ElementNotFoundError: {'title': 'Units', 'class_name': 'TTabSheet', 'top_level_only': False, 'parent': <win32_element_info.HwndElementInfo - '', TPageControl, 3742488>, 'backend': 'win32'}

3.
Code:
self.export.child_window(class_name="TPageControl").menu_bar_click_input("Units", self.app)
Error:
AttributeError: Neither GUI element (wrapper) nor wrapper method 'menu_bar_click_input' were found (typo?)

4.
Code:
page_control = self.export.child_window(class_name="TPageControl")
tab_list = page_control.descendants(class_name="TTabSheet")
tab_menu = tab_list[2]
print(tab_menu)
tab_menu.click_input()
Output:
It prints: hwndwrapper.HwndWrapper - 'Units', TTabSheet
But clicks on center on the window, not on the Units tab

I’ve added screenshots with the TPageControl and Units elements highlighted by Inspect.exe I’ve struggled a lot with this and couldn’t find the issue… Thanks in the advance for the help!

Issue solved! If anyone else has this problem I managed to find the solution by using TabControlWrapper. The solution that works:

from pywinauto.controls.common_controls import TabControlWrapper

page_control = self.export.child_window(class_name="TPageControl")
tab_control = TabControlWrapper(page_control.wrapper_object())
tab_control.select(2)

Hi, do you know what do I need to change to get TabControlWrapper working for me? My goal is to paste “text” word in a specific tab of MobaXterm app.
