Hyperlinks to internal sheets disappear after the click

[Corsari]

Hello to all the community

I have done a really simple brief test

LibreOffice Calc 6.1.0.3

Created a new file test.ods

Added 4 sheets

Created a TOC in sheet #1 mean that e.g. in

cell B3 you have “Sheet #2”
cell B4 you have “Sheet #3”
cell B5 you have “Sheet #4”
cell B6 you have “Sheet #5”

then I have selected string Sheet #2 and with Ctrl-k I have made it a link to sheet number 2,

then I did the same for the remaining three strings and linked EACH of them to the respective sheet

Saved the document

AS SOON I click ANY of the strings, it does correctly jump to the selected sheet, BUT, when I come back to sheet #1 all the cells are EMPTY

What is this bug?

Thank you
Thank you

UH-OH

I had a suspect and tried this

if I DON’T write any string and instead I JUST select one EMPTY cell and I Ctrl-k insert the link,

well, that works

I can click to sheet #2, it jumps to sheet #2 and when I go back to sheet #1 the link is still there

mmmh ,

though this looks like a bug

in fact,

If I do use a shape and make it a link (select the shape and Ctrl-k on it) , e.g. on the Sheet #2 I place a button shape and make it the “home” button to go back to sheet #1,

well, I click that home button, it jumps to sheet #1 but when I go back to sheet #2, the button shape is disappeared

If I click ctrl-z it does re appear

?!?!?!!?
