C# Selenium contains() not finding the correct element

For some reason the I keep getting the wrong file returned to me. I keep getting a file with the name FC6...

I ran through the debugger and the search variable stays FC5 the whole time, I am guessing it has something to do with the contains() function, but I haven't had an issue anywhere else.

Looking for a way around this issue, thanks in advance.

        public override void selectFiles()
        {
            foreach (string key in searchKeys)
            {
                IWebElement keyElement = base.getKeyElement("FC5");

                //get the parent of the key element
                IWebElement parentElement = keyElement.FindElement(By.XPath("./parent::*"));

                //get the download tag in the parent element
                IWebElement element = parentElement.FindElement(By.XPath("//*[contains(text(),'Download')]"));

                Actions actions = new Actions(driver);

                actions.MoveToElement(element).Click().Perform();
            }
        }

        public IWebElement getKeyElement(string searchKeys)
        {
            IWebElement element = null;

                string keyString = "//*[";
                string[] keyList = searchKeys.Split(",");
                bool firstKey = true;
                foreach (string searchKey in keyList)
                {
                    if (firstKey)
                    {
                        keyString = String.Join("", new string[] { keyString, "contains(text(), '", searchKey, "')" });
                    }
                    else
                    {
                        keyString = String.Join("", new string[] { keyString, " and contains(text(), '", searchKey, "')" });
                    }

                    firstKey = false;
                }
                keyString = String.Join("", new string[] { keyString, "]" });

                element = waitForVisibility(By.XPath(keyString));

            return element;
        }

        public IWebElement waitForVisibility(By element)
        {
            try
            {
                return new WebDriverWait(driver,        TimeSpan.FromSeconds(5)).Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementIsVisible(element));
            }
            catch
            {
                return null;
            }
        }
