Hazel now takes long time to read words within PDF's

Hi,
I've been using Hazel for 2 years now and it has been working perfectly until the other day.
I use Hazel to find words within PDF's on a network share set by rules, depending on which word is found use a rule to move the pdf to a different folder across the network. I connect to each network folder using a SMB connection.
Recently find that my version doesn't seem to read within the PDF's as fast as it used to as someone updated the Mac Hazel was running on, the previous version was read a file within seconds and now it's taking 5-30 minutes each pdf.
Also, the Hazel works fine (although slower) when there is just one pdf in the network share but when there are multiple pdf files it seems that Hazel is scanning all the pdf's in the folder at the same and not one at a time.
I've tried Hazel on Mojave and High Sierra (latest Version) and still no luck. I have forgotten the OS and version of software that worked fine.
Any help would be greatly appreciated as I rely on this fantastic software daily.
Thanks in advance
