Instead of enabling the TC interrupt in the timer object, leave the interrupts disabled, and connect an 'Interrupt' component to the TC pin. Set the Interrupt to 'rising edge' triggered and that should resolve the issue.
You can do the following to achieve 100mS interrupt. Connect the TC terminal of Timer to an ISR as shown in figure, TimerWith-ISR. And set the Timer configuration as shown in Configure Timer. Zip file attached has the pics.

The High pulse on TC will last for 1 clock cycle period of the input clock to the Timer Component.
If you are using 1KHz clock, then you will see a 1ms pulse on TC.
In the 'Configure' tab of the Timer Component, set the 'Run Mode' to 'Continuous'.
You can connect an Interrupt component to the TC terminal. Or connect it to the 'interrupt' terminal after checking Interrupts 'On TC' in the Configuration Box.
Let us know if this works.
