In version 10.6.1.3 of Toad, the table filter icon/button sometimes displays incorrectly.
The problem occurs when the right hand side of the Schema Browser is on the 'Columns' tab.
If the current table has a filter, so the icon is red, when selecting a different table without a filter, the icon retains the red colouring, indicating a filter is present.
If you then select the 'Data' tab, the filter 're-enables' and the icon is then displayed correctly.
Steps to Replicate:
1. Log into database
2. Open Schema Browser | Tables | columns tab (RHS)
3. Add a filter to some data in a table & see the icon turns red
4. Switch to another table, still with Columns tab selected
5. The filter remains Red, even if this table has no filter applied
6. If you switch to the Data tab, the filter icon displays correctly
