Possible bug in Xpath detection

[sangalaviral]

URL in question: https://www.sysax.com/download/
Xpath to be monitored: /html/body/div/div[5]/div[1]/a[1]/table[2]/tbody/tr[2]/td[1]
Version: 0.54.7
Installation: K8

The above xpath can be picked using the Visual Selector Filter but upon recheck, it would throw "Warning, no filters were found, no change detection ran - Did the page change layout? update your Visual Filter if necessary."

Verified the xpath on https://xpather.com/ and it works there but it does not work on changedetection.

If I trim the xpath to /html/body/div/div[5]/div[1] it does show content but it immediately stops if I add /a[1]
