I$\text{'}$m trying to get only the first date of the "End Date changed from" even if it's null. I did this, but I$\text{'}$m still getting additional numbers in some of my results. What am I doing wrong?

$$

DROP TABLE #Store

$$ CREATE TABLE #Store

$($

$[$Description$]$ varchar$(250)$

$)$;

INSERT INTO #Store $([$Description$])$

VALUES $(\text{'}$Store Pricing Plan #$1111111$ modified.$$ End Date changed from NULL to $10/24/2024\text{'}),$

$(\text{'}$Store Pricing Plan #$222222$ modified.$$ End Date changed from NULL to $04/30/2025\text{'}),$

$(\text{'}$Store Pricing Plan #$333333$ modified.$$ Start Date changed from $09/16/2024$ to $10/01/2024$ End Date changed from $08/31/2025$ to $09/30/2025$ Store Pricing Plan changed from NULL to Store Plan'$)$

SELECT

$$ #Store.$[$Description$],$

$$ SUBSTRING$($#Store.$[$Description$],$ NULLIF$($CHARINDEX$(\text{'}$End Date changed from $\text{'},$ #Store.$[$Description$]),0)+$ LEN$(\text{'}$End Date changed from $\text{'})+1,10)$ 'End Date'
