Error in the project modules

Hello,

I have a problem with the module projects y projects templates.

I installed the version 7.10.9 (while I even experienced the same issue while using 7.10.7), and everytime I create a task within a project it changes the startdate to one day earlier.
This only happens in the View Gant section, as when openiing only the project it shows the right start date.
Also it seemingly only appears when a “Lag” is chosen, no matter of how many days.

Any troubleshooting suggestions or help would be appreciated.

Thanks in advance
