Hello,

When you change some properties in a style, you need to redefine all styles too. Otherwise, the default styles will get overridden with the current styles.

Here are some properties that you need to redefine to the default styles:

<TimelineContentCellStyle BackColor="White" Font-Bold="True" Font-Italic="False" Font-Names="Segoe UI" Font-Size="0pt" VerticalAlign="Top">
   <Padding Bottom="2px" Left="2px" Right="2px" Top="4px" />
   <BorderSettings>
      <Bottom Color="145, 153, 164" Style="Solid" Width="1px" />
      <Right Color="145, 153, 164" Style="Solid" Width="1px" />
   </BorderSettings>
</TimelineContentCellStyle>

With these settings, the WebScheduler will work fine.

Hope this helps. Thank you.

Regards,
