This is because, True Strength Index, uses exponential moving averages which have a small cumulative error that develops over time. And as time goes by there are more bars in the chart and when you recalculate the study because this cumulative error propagates through the study calculation, the calculation result changes. This issue is explained here: Moving Average - Exponential We are going to add a new Input to True Strength Index to control the moving average type and you would need to change it to Simple instead of Exponential. Although thinking about this some more, there really should not be a problem if the first loaded Date-Time in the chart has not changed. Anyway, it is not within the scope of our support to analyze exactly what is going on in your case, but the issue would have to do with exponential moving averages.
