Reports viewed within Staffology should be a screen view and not pdf

I hate pdfs opening in browsers and bar all my browsers from opening pdfs, I want them downloaded and opened in the program I choose. Some reports that I view on Staffology are deemed to be a pdf and my browser (following my instructions) won't open them. Why on earth has Staffolofy got this stupid set-up, especially as this only happens on some reports. Staffology should be consistent and treat all reports viewed online as just being viewed and not as a pdf
