Well they were only able to observe shalltear in her blood frenzy form and retreated when she changed into her armored mode. They might have been observing Momon's/Ainz's battle but there was all that precaution stuff that Ainz did that might've blurred their information magic. They don't know the appearance of Shalltear's "casual" form.
