I am having problems syncing and the following error message occurs

[JavaScript Error: "Shortening filename to 'Retinoic acid-inducible gene I mediates early antiviral response and Toll-like receptor 3 expression in respiratory syncytial virus-infected airway epithel.pdf'" {file: "chrome://zotero/content/xpcom/storage.js" line: 966}]

Reference the last one concerning 'Neurotoxins from Australo-Papuan elapids- A biochemical and pharmacological perspective.pdf' ', I have deleted the item from the library but the error continues to appear. I have also tried reinstalling the item but still no luck!
Any help would be appreciated
Thanks
