If you don't see all of the reservations on your new web app, or your reservation form is not loading properly, there is a need for a local database to be deleted. This is completely safe, as after deleting it, the application will automatically load an updated local database.
Here are a step by step instructions to fallow on the Google Chrome Browser
1. Right click somewhere on the calendar, and choose the "Inspect" option - This will open another menu on the bottom of the screen, ( on Firefox "Inspect Element")
2. On that menu, click on the option "Application". ( On Firefox, click on "Storage" instead of an "application"). This will open a new section of bottom left of the screen.
The "Inspect" panel might also be opened on your right side of the screen, in that case, just click on the small arrow icon to find the "Application" option.
3. In this section on the left - click on Indexed DB - to extend the list of databases. You will find there 2 databases. Those need to be deleted, as they are causing the issue.
4. Click on each of the database to select it, and then you will see an option to "Delete database". Click on the button to delete the corrupted database. Do it for both databases. 
On Firefox, click on the datebase with a right mouse button, and choose to delete the database.
5. After removing the databases, you should see them gone from the section of IndexedDB - it should not contain any sub-items.
6. The final step is to refresh the page - this will force a new database to be downloaded from our server and will fix the problems.
This is a one time deal - as we have added an option that will automatically fix the problems on the new version - simply do it once, and it will work no problems!
