That last instruction dates back to XOOPS 1, where there was a config option where you could set what HTML tags were allowed for users, and which were not allowed. This probably means that the module is made for XOOPS 1 as well. This may not be completely compatible with XOOPS 2, since the core has many many changes.
In other words, it could be just a small issue and then be solved quickly, but it also can be a big problem because of incompatibility issues...
