Some information of formular get also lost. I habe entered a formular with a decimal number 0,5. It seem to work, but after saving and reopening the document the formular deliveres a wrong result. The comma in the decimal number got lost. Instead there is an "|".
Please test in safe mode, Menu/Help/Restart in Safe Mode
I used the same document and tested it in save mode, as described. Same failure, format and comma got lost also in save mode.
